[TenTec] Argosy 2

[ROLAND HOWELL]

Hi Gents

This may be a duplicate of an email already sent, however I may have 
sent it to the wrong email address, so here is my plea again.

I have just put a Argosy 525d on the bench, TX is fine on tune and cw, 
50 watts at full power or 5 watts with rear switch in low position, the 
reported problem is no TX audio on SSB, tried another mic, still the 
same.

Looking at the diagram I see mic audio goes thru' a 4558 I/c, are they a 
known problem or should I look elsewhere, going to do voltage checks 
Wednesday.

Have any of learned gents met this problem, if so what did you find.

Stay well and healthy
