Odd files - Jansen 'copies of Fender tube amps from the '60s

[tubeswell]

One for the X-files (didn't know which forum to post it in sorry, but seeing as how they are 'copies' of fender amps, I thought the Fender forum was the best fit)

Local manufacturer, Beverley Bruce and Goldie, made 'Jansen' brand 'copies' of Fender amps in the 1960s. (In the heyday of good old trade protectionism, when you couldn't buy Fender tube amps in NZ, local people started making their own versions.)

Here's a link to a little backstory from one of the techs involved in the Jansen tube amps at the time: http://www.nzguitars.com/forum/viewtopi ... =6&t=10197

Note that some of the stuff he says about Fender's amps typology in that blog I linked to above, is just plain wrong, but that main message is that Jansen 'Bassman' amps used a 12AU7 post PI gain stage on each side of the inverter (which often was also a 12AU7) to increase the drive to the output tubes.

They also used a separate PT winding for the screen supply (as he says in that blog article)
