Worthwhile Traynor YBA-1 mods?

[Kapo_Polenton]

Had a chance to open mine up tonight against my JCM800 with a hotplate... I gotta say, i know JCM's are different one to the other but mine is an 82' with 376 plate voltage and I gotta say, I'm kind of digging the Traynor MORE! There is this hard edged fizzed sound to the 800 yet both seem to use 100k NFR.

Now the problem with the YBA-1. The thing doesn't breakup nearly early enough. IF you thought the 2204 was loud, my god, the Traynor is like Hiroshima hit my basement. Everything shakes. I need the hotplate on -16 to open it up. I have already converted the preamp to resemble that of a plexi but now I'm thinking, would it be worthwhile putting in a PPIMV or going with a hotplate and dropping volume I and II down to 1 meg pots from 4 meg? Furthermore, how about a choke? What audible difference would I be hearing here?

Apart from that, I am not that interested in making a gain monster because it is a traynor not a Boogie. I thought i'd throw in a little one wire mod on a switch, maybe jumper internally, swap a few values to coax a tad more gain out of a plexi style preamp and call it a day.

Anything else you guys think would be cool or have experience with?

I had one that just had a PPIMV and I loved it...should've kept that amp...

Yup, PPIMV is definitely on the list from the info I have been able to find.. I should probably ask over at the metro forum as well now taht i think about it..

Andy Fuchs loved these when he was doing mods.

I had a jose and lar mar master volume, toggle to jumper channels, 1 meg vol pots, other little tweaks. Sounded great and more headroom than a marshall. I think a depth knob would be cool. It was louder and clearer than my marshalls. I just sold it though to fund a guitar.

Did yours have a choke installed?

Yes mine was a 90 watt YBA-1A with choke. I never heard the ones without choke to campare to
