[ARC5] Bypass Cap Question

[Mark K3MSB]

Guys –

Thanks for the info;  much appreciated!

On the transmitter, do the bypass caps need to be at the rear connector, or
can they be at the tube sockets?  I supposed the rear connector is optimal,
but from past experience working in that small area isn’t pleasant for me
(vision issues).
