[TenTec] Need Model 315 schematic, manual and dust cover

[Heinz und Hannelore Breuer]

Hi,

today I found a lonely TenTec Model 315 receiver at a swapmeet in
Hannover, Germany.
The receiver is missing the U-shaped dust cover and the internal power supply.
Maybe somebody put it on 220V, let the smoke out and tried to repair it.
He probably never finished the job and after many hands touched it the
carcass ended at the swapmeet today. I happily paid the asking price of
EURO 5 which is about $6.
I downloaded a short datasheet from the Unofficial TenTec Pages but
didn't find any further data.
So far I didn't try to power it up. Probably a few semiconductors have
lost their smoke anyhow and have to be replaced. I need a schematic or
even better a manual to figure what might be damaged. 
A dust cover would be nice too, a power supply would be additional but I
guess I can build it myself. I will even buy a Model 315 junker to get
these parts.
The dial string is slipping but this will be corrected after it powers
up ok.

Can anybody help me please?
