Retubing my TSL

[TelePaul]

Hey all, I'll probably be asking a few questions about this as the days go by. I can actually afford new tubes for my TSL 601 which I bought second hand about 6-8 months ago. I'm not exactly sure how old the amp was when I bought it, but I know I should probably have changed the tubes as soon as I bought it.

I haven't really done this before, and even though I've read about re-tubing and re-biasing I'm not fully confident that I can do it by myself. For starters, I've to get a new set of tubes. I'm happy enough to go with JJ Electronic unless anyone has anything bad to say about them? Something like this (with KT77s):

I've also watched the video on re-biasing a TSL, here

I guess I'll need a multimeter and Bias probes too. They sell them in the online shop.

What I'm asking here is that, out of those of you here that know me, do you think it's wise to attempt this myself? There's a guy I could ring who does work on Marshalls here, but if I could do it myself it'd come in at under €100 including the tubes, which would be a big saving. As it happens, I'm not at all happy with the sound of my amp, but the prospect of 'Phase Inveters in V4' scares me.

I'd say if you are finicky about your tone then do it. It'll be a skill that you can use over and again to dial in you preferred tone, especially when you retube with different brand tubes.

you can do yjis man no problem.... and that phase invertor line aint shit... they're just saying that the two triodes in that tube are mayched... no biggie... IME the sides are never very far off anyhow... there's also a little mod that would make it's own bias probe...

See this is my worry - alot of what you said went over my head

The video is good, and I know he says the TSL series is even easier to do than the DSL series...but I wish he made a TSL video!
