WTB - 6BC8 tube in EU (6BZ8, X155)

[Whoops]

Hi,
if anyone inside EU has a 6BC8 tube to spare, please let me know something I will buy it from you.
Could be also any of the equivalents below

From what I've read 6BC8 can be replaced with any of the following:

6BZ8
X155


Let me know something,
thanks

The 6BC8 is a semi-remote cut off tube which might make it suitable for use in a compressor. Certainly the ECC85 and the 6CG7 are sharp cut off tubes so definitely very different, not to mention the 6CG7 has a mu of 20 compared to 35 for the 6BC8. I don't know where you read that the 6BC8 can be replaced by any from that list but I would be suspicious of that conclusion.

edit: If you want some 6CG7 tubes I have loads of them. Happy to send you a few for the cost of shipping.

Cheers

Ian

I ve ordered a matched Quad 6BC8/6BZ8 tube set for a Fairchild Clone / Poorman 670 from DB Tubes in Canada. They have actually RCAs NOS and others on stock....

Thanks

Thank you so much for the information Ian,
it's great to know that.

This tube is to be used in as the input tube in a Retro 176 Limiting amplifier (sort of improved clone of the UA/Urei 176),

I used these 2 websites for possible 6BC8 equivalents, they list the ECC85 and the 6CG7 but like you explained the tubes are indeed different so I will not trust this sources, much prefer to trust you.

I'll edit my first post

Thank you so much mate

I have not found any source in the EU and I ve searched for hours, nearly days. Its one of the last source, and David Boardman had 5 weeks ago hundred tubes of 6BZ8 and different brands like Tungsol, Philips on stock, they are all nearly gone away. So I believe you will have the same problem like me in Austria.... Sorry bro

Thanks mate,
I've ordered 2 tubes from ebay from different sellers/sources inside EU, hopefully at least one of them will be good

Thank you

Thank you, I didn't know that store, it's good to know.

Although they state the 6AQ8 as being the same as ECC85, and Ian already explained the ECC85 was not a good candidate for replacing the 6BC8,
so it seems I should also take the 6AQ8 out of the possible equivalents list.

6AQ5 and ECC85 are equivalent. They were designed for the front end of FM receivers:

Vacuum Tube - 6BC8 / 6BZ8, Dual Triode | Antique Electronic Supply

Looks like the only real equivalent is the 6BZ8

Cheers

[Whoops]

I guess the only equivalents would be the 6BZ8 and the X155

Thank Ian

Happy with the order?

Hi, I have not tested the matched Quartet of 6BC8. They should work in the Poorman 670 build. I think in a few days the "endless" wiring will take an end and then I will test them....
They are a real critical part in this circuit and would missmatched cause in lots of noise ...

Ok, just ordered a matched pair... will be interesting to hear what they sound like!
