I could use the following parts for my T-19/ARC-5:  Final Tank Coil,  Roller Coil, and Relay K-53.

Also in the works is the use of a T-22/ARC-5 7-9.1 Mc unit.  The junk box yielded a 24VDC regulated PS that will be used for the filaments and relays.  Keying chirp might be a concern and I've toyed with the idea of a buffer stage between the 1626 Osc & finals.  

If I go this route I'd appreciate comments from those who have done this addition as to the  12 volt filament  tube used to insure equal filament current needs between the Osc. and Buffer.

Then again, by following the thorough ARC-5 data that is available, it may not be necessary to use a buffer as the T-22 is unmodified or touched in all respects and it would be nice to use it as-is.  

Thanks
