Dating fender telecaster serial
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.These mods are worth doing to any Signature/Bass-Master, IMO. CAD 3 used, bad price, amp in average (5/10) condition, Song Bird Music, Ottawa, Canada, summer 1998 US 5 [used], needed a little work but playable, cheap buy US 9.99 [used], seen at September 1998 CAD 9 [used], good condition, seen at Used Music, Ottawa, September 1998 CAD 0 [used], shabby condition, very early (pre October 1966) wrap-around type case model with tube rectifier, seen at Used Music, Ottawa, September 1998 CAD 5 [used], ca.] 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.Features silvery grey grille cloth Yorkville [...] owns Dyna-Bass #0011 and [has] used it as a promotional tool.
That part of the hand-drawn schematic from 6/1971-1974 is smudged and hard to read, but it's definitely 68K.437 volts); this may have gotten higher after 1971, but into the summer of 1971 I'd expect the plate voltages on 6CA7s to be down substantially from the YBA-1A; have the chassis sliding-in ala Fender.Last versions have that easily identified rubber and 'chrome' molding running around each end of the head cabinet; mine is from 1971 and is this last version; 1972 models have no choke; [a 1978 is] black with the black plastic fabric and [has] the baby bumper trim, [it has] two 6CA7 and three 12AX7A tubes in it [and] no fuse holder, just a red reset button I put Mullard EL34s in my YBA-1.[...] When [the YBA-1] ran on 7027s, it was a rock machine (think Black Crows, Zep, etc.).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.
