I guess I too have become one of the old curmudgeons!  I drag out 
measuring tapes and use '80s roll of Copperweld to make antennas.  I 
maintain my BC-610 and T-213 TXs, plus  the SP-600 and R-390A. (Torn 
apart Blue-Striper. Very slowly being restored.)

First rig was Heathkit SB-102, SP-600, w/HP-23(x) power supply. Traded a 
Tram D-201 for an FL-2100B.  First amp owned.  That went in trade for 
the TS-900, and the need for the HB 813s.

I find that block diagrams and schematics won't necessarily indicate 
ability to handle specific voltages.  I'd be MUCH happier having a 
Kenwood Master Parts List.  I found one for Heathkit.

Looking up relay P/N in list would indicate information as to what 
voltages for relay, and perhaps if lucky, what the contacts would handle.

However, Clif Holland, KA5IPF, would be the *BEST* source of information.
