Mesa Baron

Not a question, really, just looking to share something with any users of the Mesa Baron all-tube power amp (now sadly discontinued).

I just found THE preamp to match this high-gain amp, after trying for 10 years. It's the Promitheus Audio TVC (passive transformer volume control).

Over the past 12 years, I've used the Baron in 3 phases - back in 96-97, when it first came out, when I reviewed it for a publication; then in 2000-2001 when I bought and then sold one ... and finally, in 2004, which I intend to keep until Hell freezes over.

I've used McCormack's passive TLC-1 preamp (a pretty great match), Audio Research low-gain LS15 and LS16, Quicksilver Linestage and many others ... but something just clicked with the TVC.

Just in case anyone's still in the hunt to optimise their Baron's performance. Do note - all the while, I've been using the stock version. I have, however, messed around with the input driver tubes (AX7) - the onboard Russion Sovteks have the best punch, Tungsols sound cleaner and airier, and Mullards are just too syrupy for me ... :)

Appreciate any thoughts ...

cheers

Hi, I also bought a Baron this week just to test. Amp is in great condition but still has first original 5881 tube set. Think is not in excellent condition anymore afer all these years and I think to replace also to avoid damage of the amp or my speakers.

Has anyone listened to TUNG-SOL 6L6 G (bottle) in this amp. Is this tube working/matching with the Baron? Could someone tell me something about the mods you've written? It's possible to use the EL34 tube set without any modification or is amp originally sold with EL34 the same like the 5881 version?

Many questions. Thanks for your help; amp is very rare here in Europe so it's hard to find someone to help me.

Bye,
Marco

Hello Lloydc,

do you know how to find out wether my amp has the tri-tube mods or not? Where is difference; other restitors or caps or any other signs? You think there is no problem using the 6L6G (bottle tube) form Tung-Sol? Also think about changing the output caps audiophile Mundorf caps.

Bye,
Marco
