Old tube amp quiz

[nybbe]

Hello! I have a question if anyone of you talent guys can help me identify an old tube amp. It has 6 ecc83 and 2 el34 tubes. There is a footswitch jack on the back-panel but no speed or sensitivity control. The front panel is plexi with two channels with volume, treble and bass. The only clue is a text on the back Important
This amplifier has an output
of 60 watt undistorted, care
must be taken not to adjust
he volume controls to exceed
the handling capacity of the
speakers being used

It´s marked 1020-7A. the amp is working but no tremolo.
What the hell is this?

mabey markings on the transformers?

A picture would help a lot....or some hint towards a manufacturing country, or something?

Cheers /Richard, Sweden (too)

Actually I find info about the amp on a site in Sweden. www.edgaraudio.se
It´s an Impact 60w reverb & tremolo amp.

Thanks for your interest
