Q: my dad's friend died, and dad had been keeping some valves of his. now we've been left with about 400 valves and i'm going to sell them.my main question is what are they used for? i need to write a description for ebay but have no idea what they're for! anyone know?also, how much should i sell them for? on the box it says 11 shillings, which i worked out as ?1.32, but how much should i sell them for on ebay? there's prices on ebay that are about 50p to ?1.50 for most of them, but some are about ?7 but have no bids at all. how much should i start the bidding at?also, if you could give me any other information that i should put in the description, i would really appretiate it :)they are mainly 'Mullard' valves (the company name) but some are 'MAZDA'thanks! :D: It sounds like 1960's 70's 80's radio and tv valves. pcl 85, pl504, py800, ef80, pcl82, maybe. I through away about 100 of them about 10 years ago. I wish i would have kept them. They are of interest to vintage radio and tv collectors. Could try selling a few at a time number should be on the glass. Still used in high quality audio amps and output stage of guitar amps for warm quality sound. Good luck.

Q: Hi....my boyfriend is currently waiting to have heart valve replacement surgery and im a little worried about the whole thing...he doesnt like talking about it but if someone knows the answer to my questions I'd be so greatful!!First of all a little detail....he is 19, as far as i know he was born with this problem with his valve but it has got worse over time. he was also born with a hole in his heart but had an operation as a baby to fix this. he gets short of breath and often has pains in his chest. he says hes going to have a pigs heart valve to replace his, by open heart surgery (in a few months time). my main worry is whether the operations are always successful? and will this condition/operation affect his life expectancy??please if there are any experts in the field help put my mind to rest....!thanksshelly x: Open heart surgery is always a risk, as is any major surgery. The main risks are from infection and blood clots. The risks taper off very quickly within a few days after the surgery. Heart valve replacements are a common operation, with a high success rate. Life expectancy is generally better with a valve replacement; but not all valve problems reduce life expectancy to begin with. Sometimes the trade-offs are more of an issue with quality of life, with higher quality achieved with a functioning heart valve, so some people may be taking a medical risk to obtain higher quality of life. No one can tell you for certain what the outcome of this operation will be. The odds are very high that everything will go perfectly and he will fell better than ever before. There is a very small chance that he will end up worse To put the risks in perspective, a person i know had minor surgery to her knee - a simple 1 hour operation done at an outpatient clinic. Ten days later, a clot broke loose and she died in her sleep. I have had the same operation twice and didn't even miss more than a few hours of work. Another person i know had severe heart problems and docs said it was terminal, but an operation could prolong his life maybe 5-7 years. He had the operation and its now been almost 20 years and his cardiologist says his heart is healthy and there's no reason why he might not live another 20 years or more.

Q: Slow songs are a major factor of this this lagging sound. Note to Note. I Oil my Valves often and they still are slow. Am I just not using enough air? Help me Experts!: I am wondering on the make of your instrument. I have gone from a Yamaha euphonium to a Bach and now to a Yamaha pro model Baritone ,compensating 4 valve ( English bore) Having been previously a professional trumpet player I really did not like the long valve stroke on either of the euphoniums. The baritone has great valves albeit trickier on intonation.

Q: my pcv valve tube is broken in half I replaced it with a rubber hose does it have to be whole: no, i'm prety sure the pcv valve is to help the engine run smoothly. or something that has to do with the engine, i really dont think that is related to the tramsmission

Q: Hi, I was wondering if it takes a minute or two for the water to actually turn on after turning the valve? I've turned it as far as I can counter-clockwise but there's still no water. Is there something else that needs to be done to get the water back?: after turning the valve back on. Is there another valve upstream that was turned off as well? +

Q: Hey my sexy internet homies lt;3: I need help on artificial valves. I need to know the following things:How do the properties of the materials artifical heart valves are made from make them useful?Explain how the structure of the technology is related to the function that it needs to perform.Thanks!!: There are three of these things: the caged-ball which utilizes a metal cage to house a metal ball, tilting-disc valves, which have a single circular occluder controlled by a metal strut. They are made of a metal ring covered by a tissue, into which the suture threads are stitched, in order to keep the valve in place once implanted and there's bileaflet valves, which consist of two semicircular leaflets that rotate about struts attached to the valve housing which is the most recent type, eh? So heart valves are considered to be extremely durable. They're made of either pyrolytic carbon or titanium coated with pyrolytic carbon, and the sewing ring cuff is Teflon or polyester or dracon (probably dacron :P). They key to the materials chosen is durability because of the constant fluid flow. I see this as pure engineering, not medicine, specifically fluid mechanics: like if there are rare complications for example thrombus formation is a debilitating side effect of high shear stresses created by design of the valves. Ideal heart valve from an engineering view would produce minimal pressure drops of course have small regurgitation volumes because it's supposed to minimize turbulence and regulate the flow.

Q: 1994 Chevy K1500 P/U 5.7 liter 350 4X4 5 speed. When the truck is under a hard pull the valves start knocking, the knock sensor adjust the timing and the check engine light comes on. The code for the light is not detecting knock sensor. I have changed the pcv valve (which was suggested) and no change. This has went on for about 5 years. Doesn't matter the grade of fuel I use. Routine maintance and tune ups have been done to this truck. The converter was taken off 7 years ago because it was clogged. The truck runs rich after the timing adjust. The light resets itself when it is turned off. ( the code is saved): disconnect the positive battery terminal for a couple minutes. Other than taking it in to have it reset that is the most generic way to clear it. but it sounds like your timing advance system is not working.

Q: I had some great answers to my question yesterday... I have decided to have the valve job done... Since I have decide to go this route... I need some reassurance, the few people I have suggessed this option to have now told me that typically after a valve job other problems will start showing up. They have said that the car isn't worth putting money into and to get ride of it.: The valve job may not solve the engine problems /condition.Consult your service centre and ensure you take their advice!

Q: I pulled the vaccuum line off the valve and nothing happened. I revved the engine and held it a higher rpm and still nothing happened(no vaccuum). Does this mean that the egr valve is bad. I have been having a problem with rough idle, and keeping the car running at a stop sign. I have already changed the pcv valve and that seemed to help a little. Thanks: You have likely got a bit of carbon in the EGR that you can clean after you remove it, I usually spray some penetrating oil into the valve hold my finger over the hole that I sprayed into and turn the valve over, if it leaks the seat is dirty and cleaning the carbon out may help. also push up on the plunger several times to be sure that it doesn't stick alternate carb cleaner with penetrating oil until the valve is free and no longer leaks when inverted. As far as your question the test you described doesn't test the EGR or the EGR solenoid correctly at all. On some the car needs to be in gear to actuate the EGR, all you need to do is check that there is vacuum to the solenoid and that the EGR valve works freely. If the EGR fails to work the check engine light should be on and you can check the code to get a clue as to why.

Q: I assembled my new gas grill, but I'm not sure if the burner pipes (aka venturi) are properly connected to the valves. My assembly matches the picture in the instruction manual, but I'm not sure if the seal is tight enough. How do I know? Do I attach the propane and test? I'm concerned about the safety of doing so. Thanks!: Brush on some soapy water solution around all fittings and turn on the tank. If your not comfortable with it wait and have someone else check it out.
