What valves are pin compatible with ECC88 / 6DJ8?

Merlinb · 28th August 2009, 08:06 PM

Hi,
I want to draw up a list of valves which are pin compatible with the ECC88 / 6DJ8 type base configuration.

I know of the ECC85, 6N1P, 6N2P, but what else?

I'm not worried about functional compatibility, or different heater current requirements, I'm just looking for the same pin-configuration.

The 6DJ8 has the 9AJ pinout. Go get yourself a copy of Duncan's TDSL personal edition. Use the search tool to find all the tubes with the same pinout. There's too many to list here.

6FQ7
6922 - the Sovtec's aren't bad.

I've never heard a 6DJ8 that sounds good to my ear and I've tried a lot of them

Aha! I've not used the personal edition, thanks for the tip!

6BQ7, 6BK7, various other similar numbers like 6BC8, 6BZ7, 6BS8. Also 6AQ8, 6DT8, 6CG7, 6GU7, etc.

And let's not forget the best, IMHO, the 7308. and the best 7308, IMHO, the gold-pinned Amperex PQ or USN. I have a pair of USNs which are beyond incredible.

7dj8 AKA PCC88 is pin compatible and functionally compatible, except for the heater voltage.
6n23p/6H23, 6n1, 6N11, CCa, CV5358 and Ecc189 / Pcc189 also come to mind, though the last two are remote cutoff tubes.
Have fun!

Hi, I bought this Zaerix CCA-E88CC gold pin.
Can anybody help me to identify the manufacture of this tube?

Thank in Advance,
Kesha

If its Zaerix its probably Russian or East European. Give us a picture of the pins, getter and anodes.

The design and parts makes all the difference. Also, the rest of the system design makes a difference.

Cheers.
