My MUSIC ANGEL XDSE M9 HAS GOT 5 X6NI TUBES on THE INPUT MODE, CAN I DIRECT REPLACE THEM WITH THE RUSSIAN 6Ni P TYPES, and should I do this will I lose any QUALITY

 

[Francis Jansz]

MY MUSIC ANGEL XDSE M( HAS ALSO GOT 8 X EL34 B on THE POWER OUTPUT MODE, What Can I do To REPLACE THEM WITH A BETTER QUALITY TUBE or Can I REPLACE THEM WITH 6CA 7 or RFT EL34 or WITH 300B TUBES

 

[picowallspeaker]

Stage, not mode
300B tube is just silly, don't you think ?
Then, the quality (overall quality) is given by the system and not the single ( or group of, in this case) component

Chinese 6N1 can be replaced by Russian 6N1P. Check currents/voltages/Ri/gm/my ... and possible you can use ECC88/6922/6DJ8.

EL34 can be replaced by 6CA7 or similar. Maybe you can use 6L6 or even KT88, but you must carefully check the specs.

THANK YOU SOUNDBRIGADE

The Chinese 6N1 is a copy of the Russian 6N1P, so the best replacement would be a (or 5) 6N1P, or better use the 6N1P-EV.

Ooops, Soundbrigade came in while I was writing....


But, I dont think Ecc88/6922/6DJ8 is a direct replacement for 6N1, gm (12.5 vs 4.4), Ri (2.6 vs 4.4 k) and Max plate voltage (130v for ECC88 and 250v for 6N1P-EV).

Dear TORIVERSEN,
I thank you for the Info Provided, I will Get 5 X 6NIP-EV

In Reference to The EL 34 B (Chinese Tube) Can I Replace it Directly with EH -EL34 or 300 B, Whats The Best Direct Replacement for The EL34B. Your help will be Considered.
Kind Regards

Hi, you can replace the chinese EL34 with EH-EL34 directly, but 300b is a power triode so you can not use that in this amp.

 

[soundbrigade]

300B is a completely different tube that requires a TOTALLY different set-up compared to EL34.
I think any kind of EL34 can be used.

Have you changed the tubes in your Music Angel XDSE M9 yet? Did it make an improvement?

If you haven't changed the EL34s yet, I'd go with Mullard reissues over the EHs.
