Is your ECC88 humming or making noise? Resistance Coupled Amplifier Charts: When frame grid tubes, we write it in the description. JAN Testing is a military proces for lot qualification, which makes sure that weak production series will not pass as a whole.
Not directly compatible to ECC88, so a secret tip if you can design your won circuits. This was told to me by a retired Telefunken Ulm Employee, so I think this is very xatenblatt information.
Strangely so, but I see it over and over again. Note that the newElectro-Harmonix A is now available,and it does not requireany rewiring to use.
The Big Tube Data Page
Now of course manufacturers could still sell such tubes on the commercial market, but the military refused to take those. These appear like that. On internet auction sites, tubes are re-labelled, retro-gold plated, re-branded and used tubes are put in re-printed new boxes with the stamps ne-newed. Even with top-name amplifier manufacturers we see the same old errors, resulting from arrogancy, like not reading a datasheet. Unfortunally a big item particularly with this tube number.
This is not possible for the most wanted part numebrs. So you can see it yourself. Only do these measurements inside your amplifier, when you have experience with this. All others are gone, gone, gone.
Sovtek 6B4-G and 2A3 are slightlydifferent. This tube excist as normal grid tube and as frame grid tube. Check also next item, below here.
Clear white print like new, from spare equipment. Lucky on internet auction sites. This batch had very good values. Note ifyou already have an RCA tube manual, and if the tubeslisted on the RCA charts in the back are same as here, the pageswill be the same as what you already have. Also read here Uh-k.
Click Here for sheeton Sovtek 6B4-G. This is the reason why JAN tested tubes are so often agvailable as commercial ecv88 also!! Note that all Philips subsidary companies Mullard, Valvo, etc and allfactories that made tubes under Philips license used these codes Ei, Toshiba,Siemens, etc so it’s not limited to European Philips tubes.
Everything you want to know about how tube specsare determined, from datrnblatt shock testing to altitude testing to salt spraycorrosion resistance.
This is a much improverd version of ECC88 made, with higher voltage capabilities, higher plate dissipagtion, and better in many many ways. So vatenblatt four systems of this pair are the same. Anyway, not reading the datasheet may work with most tubes, but not with all.
Interesting detail with the tube box. We have Money-back guarantee on those.
JJ Electronic – E88CC / , 6DJ8 – gold
KT90 Note, larger 2 pages wide files, about 80Kbytes each. Curve plots for popular current production12AX7’s: Some tubes from equipment are sometimes actually never used. The rejects were probably sold a standard 6N1P, this is normal. Frame grid wires can be as thin as 10um, which is technologically speaking a masterpiece of fine mechanics. Elektronska Industri, former Yugislavia. Sorry, only one tube left. Large dimension ECC88, datenblwtt higher dissipation.
