Best tube upgrade for Peavey Classic 50

[Steven Welborn]

Ive been noticing some harsh harmonics in my Classic 50/212 lately. Maybe it's a good time to upgrade the stock tubes which are currently three ElectroHarmonics 12ax7's and four Sovtec EL84's.
I searched for options so far:
Preamp: Tesla/JJ for the 12ax7's ?

Poweramp for EL84's:
1. EI Elite
2. Russian EL84 M(military)
3. JJ
Also a dumb question: How do i make sure bias is correct? thanks

Steve,
I have a Classic 50/50 head. I retubed with: Sovtek 12AX7LPS and Tesla JJ EL 84. I got them from thetubestore.com Tell them which amp you have. They will match the sets. I think the bias is factory set? And not adjustable. These new tubes were a definite upgrade.

I retubed mine with matched JJ Tesla and was very happy. I'm having a brain cramp and can't rembember the name of the place I used but he had excellent service. One of the tubes blew when I turned on the amp. He overnited a replacement free. I replaced the stock speakers with Reverends at the same time. I use this amp for six string and it rocks! BTW.. I used this last week at practice for my steel and it really sounded great.

Yay! I remember. It was this fella.

I emailed him and explained that I wanted a very clean tube sound. He hooked me up. These come in different ratings for different type styles.

I have a quick question for Mike: I have a Triumph 60. Is the bias fixed in this also?
