This is an exceptional integrated amp from the Arthur Steidinger Company
(ASCO).
You can find more
information about the outstanding power amp section on its own site (click
here).
The preamp section and
the power amp are mounted on two different chassis and a multi connector
cable (with "Messerleiste") supplies B+ to the preamp from the power amp
which incorporates the power supply for both.
The preamp uses 2 ECC83
tubes for the RIAA preamp, 2 ECC808 in the tone control and 2 ECC83 tubes in
the output section.
There are a lot of
filter switches and many controls (too many?) to change the frequency
response.
