OT Mirage D1010 432mHz Amplifier

[Lewis Phelps]

I apologize for an off-topic posting.

I’m trying to find a schematic diagram and board layout for the Mirage D10210 432 mHz amplifier. I just bought one on eBay. Although it generates power into a dummy load, I think something’s wrong with it because it has no idle current.  The amp is supposed to be biased for SSB but doesn’t seem to be.  There are three ‘thumb wheel” pots on the board, two of which appear to possibly be bias current settings for he pre  amp and amp. However, tuning them does nothing to change the amp’s total current draw (which is 30 MA, presumably for the Power On LED).

thanks in advance; please reply off the list.
