Carver receiver part I.D.

[Scanlines]

Hi there;

I've got (I think) an early production Carver receiver, it has no listed model number on the cabinet just a series of patent pendings. The only thing close to a model # is BEY645.

There's a shorted 2SA1302 output and also 2 burned, black and misshapen resistors. Look like half watters.

I don't know if anyone has a print on this but the resistors are numbered R549 and R539. The former is in a driver circuit, the other in series with a zener in a power supply. I've searched quite a bit on the web, but I can't come up with much on this one so far.

Thanks in advance for any help.
