Look at this photo of the inside of my Traynor YBA-1

Look at the size of the transformers. It's not wonder this thing weighs so much

. I put my fist in their for scale.

Do you have any idea why they are so big?

Hahah I should get some pictures of my Sovtek Midget 50H's transformers. The head is about the size of a lunch box and weighs about as much as oh say a car

Gotta love it though.

Ya that sounds like the YBA-1. It's not that small, but it's a lot smaller than something like a Marshall head. You'd look at it's and think it's fairly light, but when you go to pick it up it suprises the heck out of you. It could really almost use side handles on it for carrying it.

One prime consideration in buying an amp...if you want power, buy weight. Without big iron in the trannies, there will big no big sound.

Yes, it is a BASS amp.

Does that one have a tube rectifier? The earliest models with a tube rectifier had GIGANTIC transformers. The next version ('67 - '70) just had huge transformers. Best 5F6-A knockoffs ever, IMO.....

No I THINK mine is either a 69' or a 70'. It's before they put fans in them, but after the tube rectifier.

I've had it since highschool, when I orginally played bass through it. It never occured to me till they started getting so popular recently to use it for guitar. It was actually out of commision for the last 3 years and I just got it all fixed up. IMO they sound a million times better as a guitar amp than a bass amp.

They actually sound great as a bass amp for recording, too, but obviously don't have the required output for the band - unless they are REALLY QUIET.

The ones with the fans are YBA-1A's. They really should have given it another number, because there continued to be a YBA-1. However, THAT YBA-1 has a very small output transformer in comparison to the older units. It was intended for guitar, even though it was still called a Bassmaster. The cathode follower that drives the tone stack was converted to a gain stage, and a notch filter was inserted. This gave the amp more of a "Mesa-Boogie" tone. They sound very good if you change the circuit back to the 5F6-A topology.
