Telegraph relay ?
relay spring balance and adjusting tools ?
(I like the TTL gate hi)

I'll use transistor switching really, Graham - the relay is
metaphorical...
I can just about manage that...solid state 12AX7, no problem!

Well that's the problem, we all know what the kit can do , but
there are only a few who can tap the keys and make it perform ..
I think your keying relay would be OK for OP8 .as long as the pull
in and release times are well matched to retain the envelope shape
..
I think pulse 'jitter' would be a problem on the higher (shorter)
versions ...... could you not use blocking keying or a pin diode
switch ?
