I'll use transistor switching really, Graham - the relay is metaphorical... I can just about manage that...solid state 12AX7, no problem! Martin GW3UCJ. ~~~~~~~~~~~~~~~ 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 ? |
