I have swapped out the 4M volume pots for 1M, and put a 47K resistor in the NFB loop. Professional repairman required, although schematic is included, weird defects possible. The YBA-1 serial number is 8011108 the YT-15 serial number is 7125596.

It probably has a bit less bottom end and more mids and highs now. It must have been one of the last YBA-1 Traynors made.

The 2nd one I bought [...] was totally moded for guitar with extra pots on the back and stock EL34s. I [...] have [an YBA-1A Mark II amp] that goes with [the YT-15 cabinet] and it's all sounds great. i believe, though i am not sure, that these 1a's operate in class "a". Other than the old no ground power cord and serious shocks and buzz it sounded better than what i was using.

i stuck a master volume on the back, jumped the channels, and cranked both channels to 7-8, plugged in my custom shop '61 reissue sg, and it kicks so much ass [through 4x12 25w greenbacks] its indescribable i bought both a 1971 yba-1 and a 1972(? [...] the yba-1a is currently beating the snot out of an old mesa 4x12 with 90 watters in it. this would make sense to me considering how very crushing it is and yet chimey. The only real problem was it seemed to be blowing fuses.

] 0 [used], very early model, the serial number is 0278, which places it in 1966, uses 6CA7 tubes as specified in the tube chart, no tube rectifier, and the marshall style phenolic turret board, also, it has the hole in the chassis for the tube rectifier socket, but it is blocked with a circular steel plate, the 5 volt rectifier heater winding at the power tranny is cut about 2 inches out, December 1998 Rating Very good one. I have a 1977 YBA1 with a matching YT-15 cabinet [...]. It's probably not worth a tird as a collector's item but this amp really screams. I rate my YRM-1 second to my YBA-1, because it does not have as much balls.

This must have been one of the last real Traynor amps made... Also, my YBA-1 sounds great at all volumes, including low setttings. 1965 or 1966 YBA-1 Bass-Master (old wrap-around style case), logo 1965 or 1966 YBA-1 Bass-Master (old wrap-around style case), front view, angle 1965 or 1966 YBA-1 Bass-Master (old wrap-around style case), front view 1965 or 1966 YBA-1 Bass-Master (old wrap-around style case), back view 1966 YBA-1 Bass-Master, chassis 1966 YBA-1 Bass-Master, wiring 1968 YBA-1 Bass-Master (serial number 2xxx), front view, angle 1968 YBA-1 Bass-Master (serial number 2xxx), front view 1968 YBA-1 Bass-Master (serial number 2xxx), logo YBA-1 Bass-Master, catalog page YBA-1 Bass-Master, catalog page YBA-1 Bass-Master, schematic 10/1966 YBA-1 Bass-Master, schematic 6/1971-1974 YBA-1 Bass-Master, schematic 5/1974 - Please note: This schematic has a serious error in it.
