1 - Ultra RARE RED TIP Amperex ECC88 6DJ8 holy Grail Frame Grid D Getter 1958

Description: The only one I have- and will likely ever have had. I am sure I’ll regret selling this one. You can’t find them anymore and they are a lifetime me tube. Bragging rights ✅☑️ It’s got about 30 hours total on it. That’s a generous estimate I’m certain it has less. You’ll never have to buy another one. Saving your ears…… and your dimes. You can’t put a price on quality - tubes today are made cheap. They want you to have to buy another one and another one …….. possibly even every 3 months. Having that said you buy four “new today tubes” on a budget & you’ll spend more money on those tubes than one good one over the life of your amp. Our ancestors, well they made tubes to last a lifetime. Rare red tip special quality amperex! Silk screen super fragile and only the factory codes and ecc88 6dj8 are present- parts of holland no logo left Heerlan holland delta symbol date code ECC88 / 6DJ8 Telefunken SELECTED TUBE with red tip New Old Stock white Box. Fabulous original 1960s vintage white label German made ECC88/6DJ8 This had the red, painted tips indicating they passed stringent after market testing for use in industrial and hospital equipment. Ultra low noise, matched triode sections. Carefully matched to within 2 percent. Tv7 tested NOS TUBES Test Results are available upon request if not photographed in the listing or already stated. 90 % of our tubes are Tv7 tested Tubes tested on tv7u the Military standards were tubes needed to meet 60% (minimum value) All our tubes have been tested for GAS SHORTS TRANSCONDUCTANCE & EMISSIONS Please see my notes on noise tests below ***We have a few different testers available to ensure the quality of the tube***** (as some tubes can not be tested on the tv7) Tv7 testing is tedious and I spend 12-13 hours a day testing tubes and double testing tubes - if you notice a mistake(like a picture doesn’t match the title) please be gracious and let me know. UNLESS PHOTOGRAPHED WITH THE ORIGINAL BOX- tube will come in repackaged white boxes- 50-90 year old cardboard packaging doesn’t hold together well. ***we have over the last 20 years amassed a huge collection of vintage amps/ parts / tubes and have decided to downsize that collection Every tube has been marked for tracking and security purposes - these marks wipe off easily and without the mark no return will be accepted - Sound quality is tremendously SUBJECTIVE. Please let us know what your intended application is prior to purchase if you have a specific sound in mind and/or just don’t know what you want. NOISE TEST. This is a very marginal test, only for special checking. This test needs sound amplification; hearing listening to noise with headphones would indicate a real disaster inside a tube (THE shorts test WOULD already BE evidence OF THIS) some testers do have noise test jacks that connect to either headphones or to the antenna/ground terminals of an AM radio. There is nothing wrong with performing that noise test. *****this test is not going to tell you whether the tube will be silent in your SET (single ended triode) amp or in anything else. *****Ultimately, the best way of testing a tube for microphonics is in an actual chassis or amplifier similar to one in which it is intended to be used.” Since amps have a wide variety of circuit designs and tube placement, this test is most effective in YOUR AMP or one that is almost identical. Hence, most people advertising tubes as tested for Noise or Microphonics are probably NOT testing them in any meaningful way for you. “Noise” and “Microphonics” are often buzzwords for other issues. (Shorts/ leaks) -there is a small percentage of tubes that have a problem with noise but far less than most people think. *****In properly designed circuits objectionable “tube noise” is seldom found. ******* In other words, it is a rare tube that will be noisy when used in most circuits. Always check the data sheet of the tube you plan to use. Tube testers and noise testing- Tube testers do not test for these problems in the manner in which you think, except to the extent that a tube tester with sensitive leakage detection will find far more “noisy” tubes than a tube tester with only “fair” leakage sensitivity, to the extent that the noise is due to this problem. Listening through headphones to tube on a tester is half as good as putting in amp and listening for noise. 1. RETURNS: I want you completely satisfied with your purchase from me. I will bend over backwards to make sure that you are a happy customer, prior to and after purchase. PLEASE message me BEFORE you open a return. 2. PLEASE NOTE: Tube silkscreen (lettering on the tubes) is VERY fragile. It can be wiped off and destroyed VERY easily. RETURNS ARE NOT ACCEPTED BECAUSE YOUR TESTER SAYS SOMETHING DIFFERENT THAN MINE. If you don?t like the sound of a tube, so long as it is still in the same condition as arrived message me and I?ll work with you
