[Kenwood] Kenwood TS-820

[Pcj3bw at aol.com]

Greetings to all!
 
As of today I am a grateful new member of the Net!  I will be even  more 
grateful if my fellow hams come up with an answer to the following  dilemma!  My 
poor TS-820 appears to suffer from a "motor boating" AF-AVR  board.  More 
specifically, Q3, AKA TA7201P, MAY be the source since all  discrete components 
have been replaced or eliminated as culprits.  However,  Toshiba sees fit not to 
make Q3 any more and now Kenwood's replacement kit (part  # W05-0257-00) is no 
longer available either!  Alas, no Toshiba part, no  Kenwood kit, no Kenwood 
AF-AVR board.  Now, have any of you out there in  ham land run into this heart 
rending situation? If so, pray tell what to  do?  How about them big thick 
National, NTE, RCA, ECG or  other semiconductor books us old guys usta use back 
in the 70's to match the pin  out on the schematics when the parts list only 
showed p/n's that didn't have any  replacements!  Might one of you have a sub 
book that may contain  a suitable amp sub for Q3?  Would appreciate any info 
that would  give me an alternative to using my 820 as a boat anchor So how's 
about  it, can someone suggest what to do about Q3?
