Superscope A-245 Service Manual

Hi Folks.

Any body got the Service Sheets - Schematics for Superscope A-245.

Or the Service sheets for any other identical Model.

Also Anybody have an image of the underside of the PCB. The unit I have is the 240v model and there is a 3 watt 560 ohm resistor fitted from the Transformer secondary Brown wire to the reservoir cap. Thing is though the wire has become disconnected and I am unsure where to solder it to. The + or -. Hence the need for the image. Some A-245s do not have this resistor so I am wondering if it is a mod of some sort.

Regards to you all for 2015.

Re: Superscope A-245 Service Manual

Thank you very much for access to the Superscope A-245 service manual. It has been a great help and I have made very good progress in restoring this lovely little amp which I bought new around 1974.

There are two pages missing from the manual. Pages 6&7 which will contain componants specifications and referance numbers along with wiring diagram for the transformer to set it at 240volts. Any chance you might have these pages.

Best wishes.

I dounload this one page by page.But the file was with payment and last pages did not open at all.:(

I Understand.

Thank you for the file.

It gave me enough information to resolve a few problems in the circuit and also I figured out what was going on with the resistor mentioned above. It was to reduce the voltage to the bulb and was fed FROM the + side of the reservoir cap. I have removed it for now and I will consider it again when I decide what replacement bulb to install.

Regards.
