NOS 33GY7A vacuum tube radio TV valve TESTED

One  new-old-stock valve, 33GY7A. A damper diode-beam power-endtetrode, on a  Dekar Compactron 12-pin base, circa 1961.

Two available, both Toshiba. Message me if you want more than one, so i can send you an offer. Multiple purchase discounts apply, except where the 'best offer' option is used.

Please note all valves i sell are individual valves; they might not be matched, and are never sold as such.

Each valve has been tested using a 'Superior Instruments Model TW-11' valve testing unit, coupled to an Eiko adaptor for testing Compactrons, and has  passed  both the shorting and qualitative tests. 

Meter picture is a stock photo, intended only to illustrate that the valve has been tested, and should not be interpreted as indicative of actual test results.

NOS, or new-old-stock, does not necessarily mean it looks like brand new, as if it just came out of the factory, like some people think. In reality, an NOS valve may have been taken out of its box hundreds of times over the last 70 years for inspection or testing. The boxes may be dilapidated, the valves may have fingermarks, pins may show signs of being repeatedly fitted to testing machines, there may be corrosion of pins, the valves may have been "cleaned", all but removing any identifying labels, and so on. This does not, however, alter the fact that they are unused stock.

Any questions please ask, I will do my best to answer.

International bidders - you are most welcomed, but you MUST either wait for an invoice, as postage cost varies with location and method (expect between $15 and $43 AUD usually), or ask for a price first . Postage from Australia is one of the world's most expensive - please do not ask to cancel a sale because you didn't ask about postage first ! I will only post to the address listed on eBay and-or PayPal. Any import duties, levies, fees, etc, that may be imposed by the destination country, are the sole responsibility of the buyer, and no, I will not falsify the documents. Insurance and tracking are heavily encouraged on all international postage. Cheaper uninsured untracked postage is available; my packaging is excellent, but if it gets lost or damaged in transit, on your head be it, I will not be liable.

Please visit my eBay store.  Combined postage is welcomed. Generally it costs about the same to post ten valves as it does one, except where it involves some of the ancient huge metallised ones, for example. Asking first is best.

My apologies to those who select 'local pick-up' to avoid postage, then want it mailed for free. Ain't gonna happen !

Perhaps you have a 'wish list' of valves - message me, I may be able to help. Hundreds yet to be listed, with more stock arriving all the time.
