This c1972 YBA-1A Mark II Bass Master Head is in very good condition. One of the top cover and one of the side chassis mount screws are missing. The circuit breaker was replaced with a fuse holder with 3 amp slo-blo fuse. Cosmetically there are “scuffs and marks” here and there, all the patina earned by age.

These Traynor amps are one of the best tube amps made. A great punchy bass amp. Equally at home and famous as a guitar amp, and designed to be an amp tech's dream. The top cover easily comes off exposing all components except tubes and transformers. Plus the schematic (missing on this one) was glued to the inside of the cover. The YBA-1A features dual pairs of inputs, dual volume controls, bass, treble, high and low (mid) range expanders, the tubes were 2 6CA7 outputs and three 12AX7A's in the preamp section. Output of this iconic beauty is 90 Watts @ 8 ohms. The earlier YBA-1 output was only 45 watts, YBA-1A is 90 watts (yes a pair of EL34/6CA7 can do 90 watts at 6-700 volts).

Founded in 1963 in downtown Toronto, Yorkville Sound was formed out of the back room of the first Long & McQuade music store. The repairman at that time was Peter Traynor, and his first development was a Bass Guitar amplifier, the Traynor Dyna-Bass. From there the Traynor line of Bass Amps have had a very successful and dynamic growth, attracting attention not only in Canada, but the USA and worldwide.

Like the FenderĀ® Bassmans of the same era this is a great sounding bass and/or guitar amp, very warm with lots of punch (maybe more punch than the BassmanĀ®, and at least as reliable)  These Traynor amps are a great find and a great value!

***Please note: we do our best giving descriptions of used pieces. We have found it impossible to describe every mark on an instrument or amp that is not in the "mint" category. Also, what's important to you may not be important to someone else. For example, you may say, "I don't care what it looks like as long as it plays or sounds well." Another person may say, "Body cosmetics are very important to me so tell me about every scratch, nick and blemish." So, please ask the questions that are most important to you. If you ask they will be answered. They are free and there's no limit. Additional photos can also be made available.
