Help restroing my new Heathkit HW-5400

[Guy G. Giacopuzzi]

While I own and use a 5400', I'm not an expert...but just a couple 
thoughts....were you aware that the rig ever worked?    The 5400' is 
very complicated, and a good number of them didn't work...the fellow at 
RTO is an expert on them, but the first thing I'd think about is a 
wiring error, or a misplaced component on a PC...I've used both the 
ElectroVoice 638  (a la Heath...) and the D-104 with a high impedance 
cartridge....both work well...I also wouldn't immediately jump to the 
final transistors, as my memory says since this unit has SWR protection, 
they're much less of a problem than on the SB/HW-104 series....
