Blues Junior transformer upgrade

[Oddvar]

Is there any tip about a  Blues Junior transformer upgrade, bot OP and PT?

I recently installed a Mercury Magnetics custom replacement OT in a blues junior and it really opened that amp up. Client is very very happy with it. The amp also has the Bill M mods in it. I recapped that amp as well with F&T electrolytics. You can see the size difference.

Personally, I feel that the stock Power Transformer (PT)  in the Fender Blues Junior is sufficient and wouldn't be a factor in making it sound any better. YMMV.
