Traynor Bass Master YBA-3 vs YBA-1A

YBA-1 was basically a clone of a 50 watt Marshall 1987 circuit. Probably the 1986 Superbass actually...I'm not sure. Later there was the YBA-1 Mk II which claimed 80-90 watts after some circuit tweaks. I'm not really sure how this was possible because that amount of output power exceeds what the power tubes(2x EL34) would be capable of. YBA-1s sound good with bass, but they don't have a lot of power so just like the Fender Bassman, it became more popular with guitarists.

 

the YBA-3 Custom Special was more of a "real" bass amp and it claimed about 130 watts from 4x EL34. It was heavily overbuilt and I've read that it's possible to use 6550 tubes after a few parts substitutions, to get something like 200 watts. This amp had very overspecified transformers which allowed for this. There was the YBA-3 Super Custom Special too, a pretty rare bird which used 6KG6 tubes, normally used as horizontal deflection amplifiers in TVs. In this application they were able to claim 250 watts from them.

+1, a good summary overall, saved me the effort

A Super Custom Special sold on the Bay for about $1,600 recently..

As far as the 50 watters; guitarists really have messed the prices up. Many of the YBA Bassmasters aren't even listed under the bass amp category.

That's {censored}ing crazy. They're great amps, but not that great.

 

I had the non-Super YBA-3 - I put 6550's in it and it was loud as hell. The EQ is a little weird, but they're fun amps.
