I ran into an old radio repair shop and he has a few pieces of the following tubes. He didnt show me the tubes but gave me a list. I picked up a couple of BEL ECC88s though. Most of these are NOS BEL tubes (thats an indian compnay that made tubes in 70s with mullard tooling). Please let me know if any of these can be used for audio purposes. He is asking for 2$ a pop. Cost is not much and I would like to pick up whatever if it can be useful for any audio purpose in future. I am a total tube newbie by the way, just getting my feet wet.

ECL86 is great for a power amp.
PY88 can be used for tube rectification.
UM84 is a 'magic eye' can be nice to make a VU meter with

Hi,
THe ECL86 is a combined triode preamp tube and pentode power tube.
Great for headphone amplifiers and also small valve power amplifiers.

thanx, will pick up EL86, PY88, UM84.
found other numbers for the remaining tubes
EF41 is the same as 6cj5/HF61/W150/7F16 and is a pentode rf/if stage.
UBL81 - typo, I think this should be UBC81/14G6. triode/dual diode.
UBF89 = WD119 = 19FL8 = 10FD12, Double Diode Pentode, RF/IF Stage, Controlling
UY85 = 38A3 = U381 Half-Wave Rectifier
could not find any info on ECL88

ECL86 = 6GW8.

ECC88 = 6DJ8, a great dual triode widely used in audio

I've never seen an ECL88 !

The EF41 is a variable Mu pentode, so it would introduce high distortion as an amplification stage.
However, it might make a good current source, so there may be a use for it.

i already got some of the ecc88s and 6n23p.
i will probably pick up an ecl88 and post a pic here.
that was again ecl86, typo on my list.
found another good shop, picked up quite a few tubes🙂.
Saw a couple of large tubes, BEL-2a and BEL-2a-1, one tube each. Found no info on the web. Any good? are these variants of 2a3?
Also saw 3 gec a2426. No reference to these here.

some pics from my crappy mobile:
An externally hosted image should be here but it was not working when we last tested it.

Those large ones look like equivalents to the 3B28, which is a high voltage xenon gas half-wave rectifier. Good for DC power supply in the 1000-1500 volt range.

thanx, i will pick these if the price is good. How much power can be expected out of these, wouldnt like to use more than 4 in a build.
Also saw an 813 single piece, can that be used in guitar amps?
Thanx, good thing you knew about this, or I would've picked these up blind due to the number 2a🙂.

I'm in the process of building a SE guitar amp.
Beware, however: the filament wires are very brittle. They won't survive rough handling as is common with instrument amps.
Another thing that makes it unpractical is the HT ov 1kV...
