[50mhz] Lunar Pre Amp

[Ray Keefe]

I haven't been able to locate any info on the usual sites about a Lunar 
PAI50B 6 meter receive preamp. Mine just went dead recently after a 
lightening strike near my house recently. (At the same time I also lost 
3 of the 4 ports in my dsl/router and 4 of the 8 in my other network 
hub, along with a tv antenna amp).

I opened it up and checked the only transistor in it and found 12vdc on 
one lead and zip on the others, after unsoldering it (it's mounted 
upside down through the pc board) to read the numbers on it to find a 
replacement. It's house numbered and no cross reference. I did find one 
cooked resistor in the rf sense ckt that I used SWAG to find the value 
and replace it. Didn't make any difference, still deaf on receive and 
the T/R relay still works.

Does anybody have a schematic for this unit, since it appears that Lunar 
has gone bye bye a long time ago.

Thanks
