[Amps] Alpha 374 T/R relay upgrade

[Scott McDonald]

I've finally resurrected an old original Alpha 374 and find it to be a pretty nice amp except for the T/R relay being incredibly loud.
I would like to upgrade it to something that sounds less like a gunshot.  I've got a couple used RJ1As, but have read that's over kill on the input side.
What's the current wisdom for improved T/R relays, with ease of modification and eliminating the loud clap being high priorities?
Thanks for any ideas.
