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
Valves (we call them 'tubes' here in the US, but 'valves' is actually a better description of how they work) were used on all kinds of electronics up to the 1970s. Radios and TVs mostly but also musical instrument amplifiers, PA system, etc.etc. In fact some high-end 'audiophiles' believe valves give you a better sound, so even today there are special (very expensive) amplifiers for both stereos and for guitars, that still use them. Only certain ones though, the ones that do final-stage amplification. And they still make the valves for these. People will want them for restoring old electronic gear, and to keep on the shelf in case one of theirs dies (they have a limited life). I have no idea what they're worth, but the answer to that question is: Whatever someone is willing to pay for them. So you have a few choices. Find shops that restore old electronics and call them and ask if they have anyone who would asses your valves, or even better, if they're interested in just buying the whole lot of them as a lot. Or go on EBay and look for the particular numbers and see what they've been selling for.
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.
Valves...or as we call them over here in the states, tubes...have a huge number of uses. These were basically what we had before we had transistors. There are tubes that regulate voltage, tubes that perform logic operations...audio tubes, tv tubes. What each tube does is pretty specific to the type of tube. Each one should be marked with an indentifying mark...such as 12AX7..or what you might see, ECC83 (just examples). Here's the great thing. You don't really need to know what they do. The people that are going to be buying tubes pretty much know what they're looking for. All you're mostly interested in listing is the tube type. You can get fancy, look it up and write down what kind of tube it is. However, you can't really nail down one application. I have tubes that were used in the RF amplifier section for VHF that, surprisingly, make EXCELLENT audio amplifier tubes. They have a wide range of uses...and for selling purposes, you only need to tell people the following: Brand of type type of tube (tube designation). You can include some information if you want...I'd make sure you mention they're untested unless you have a tube tester. But, for the most part, the people that would be interested in buying these things in the first place are already going to know what they're for. They're not something bought by the general public..it's a niche market. What you'll want to do though is look up those same tubes on OKorder to get an idea of what prices are going for. It's entirely possible you have a tube or two that are hard to find in todays market and would bring you MUCH MUCH more than the 11 shillings it retailed for. Case in point...I have a tube that sold brand new in the 60's for around $2....today..that tube can go upwards of 200 because they're not making them anymore. Oh...and make sure you throw the term vacuum tube in there too to get it in broader search results. I haven't heard anyone call them valves....unless they're from the UK.
It depends what they are, specifically. Valves used in TVs or RF receivers are not worth much. Audio and RF transmitter tubes might be worth something.
sound like the needle and seat in the carb is caught open and your new gasoline pump with solid tension is flooding your carb. take carb aside sparkling all passages with carb air purifier and then blow out all holes and passages with compressed air could restore subject.
