M135 retubing and eventual modification
 

Hi,

I am the owner of a set of Quicksilver M135 monoblocks which I purchased used about 10 years ago. I would like to retube them, and I was interested in a thread about substituting Russian tubes -- the 6p3s-e for the EL 34,s.

I am not, however, competent to evaluate whether this would be a good idea on this amp, nor what modification it might entail. If anyone has a suggestion I would appreciate hearing from you. Moreover, if anyone has a recommendation in the Montreal (Qc) area for someone who could work on the amp, please pm me, the amp has some other "issues" that I do not feel competent to repair

Sincerely

John in Montreal

Take the safe route. Install "reissue" GEC KT77s. The KT77 is a direct, drop in, replacement for the EL34. OTOH, the 6П3C-E (6p3s-e) is a member of the 6L6 clan.

If you need some kind of repair work I would get in touch with Mike Sanders of Quicksilver.

Welcome to Quicksilver Audio

I wouldn't use the 6p3s-e. I tried them a few years back. They started to sound weak (bass shy) only after couple of months. They're dirt cheap however. If you want a good Russian 6L6, I would go with the Winged C's.
