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.
Runs on less than 440 volts, weighs 39 pounds Dimensions: 8"x18"x10" (HWD); weight: 40 lbs. (source: Catalog) Silvery grey grille cloth; Original layout was very close to the tweed Bassman and the Marshall JTM-45 50-watt models; noticably huge big heavy transformers are a Traynor hallmark in these units up till the approximately 1972 models; Early models were tube rectified (5AR4) and used two 7027A power tubes.They feature a 'flip-top' design that allowes the top of the head to open like a lid.Better sound as a Fender Bassman; lower powered, would work just fine in a blues or lower volume setting (when used for bass or guitar). ] 0 [used], a 1978 YBA-1 together with a 1977 YT-15, both mint [US?] 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.Next to that is a nice Silvertone Mosrite with slider controls. Then two sweet GOYA Rangemasters and a wacky Galanti. Next is one of my current favorites, a 6-string Espana Viola shaped guitar. This guitar was also made at the VOX factory, and shares all the same parts and finish ast the 335 style Espana pictured way up above. Next, a MINT 60’s Airline Barney Kessel featuring the very cool “Kleenex Box” pickups, another current Custom Shop Reissue. This is exactly the same as the Univox, but was imported to Canada under the brand Raven.
You can see the inspiration for the Sidejack Series in many of these guitars. Then, a 9.5 Silvertone Mosrite and a VERY odd and curious guitar labeled CONTESSA.The Airline Guitars were sold through Montgomery Ward.Below: Perhaps my favorite 1960’s guitars, the Domino’s.Suddenly, electric guitars were #1 on every kids Christmas list.Companies that had been manufacturing Accordions for 20 years, retooled for electric guitars.The Galanti, on the other hand, is quite a rare bird. I found it in a shop in San Diego but they were asking around 00 for it. Next to that are a couple of Norma’s and another attempt at copying the Burns pickguard. Next to that is a Hi-Lo (also available from Ibanez). Below: As you can see, we got our walls painted the other day, hope you like it! This baby looks, feels, plays like no other Bass from its time.
