Lowe HF SP-150/AP-150
I am searching for a clear copy of the SP-150 (AP-150) circuit diagram. All I can find on the Internet is a fuzzy copy where I cannot read the component values. I am trying to repair an AP-150 where everything works except the S meter. Hard to trace things out without a readable circuit diagram. Thanks! Kim - K7IM Blakely Harbor, WA, USA

Sorry I can't help Kim: I suppose you've tried on

After I posted the request I found a fairly readable one on that website, so yes, now we have a decent copy and am making progress. Looks like Diode D-4 is toasted, having a new 1N914 coming from Amazon today, should be able to switch it out later today. Thanks!!

Just for the record, here is the reply Kim had from the group:

The AP-150 was simply a name change to the SP-150 for marketing reasons (snip) the schematics are available in the files section
