Members REMUS Posted November 5, 2007 Members Posted November 5, 2007 Can anyone outline the differences for me?
Members der oxenrig Posted November 5, 2007 Members Posted November 5, 2007 I'm no Traynor expert, but I know the 3 has more power.

Members bikehorn Posted November 5, 2007 Members Posted November 5, 2007 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.

Members REMUS Posted November 5, 2007 Author Members Posted November 5, 2007 I'll keep my eye on the YBA-3 then, awesome link takeout!
Members Deacon_blue Posted November 6, 2007 Members Posted November 6, 2007 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.
Members takeout Posted November 6, 2007 Members Posted November 6, 2007 A Super Custom Special sold on the Bay for about $1,600 recently.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.
