I have replaced the output stage and the biasing diodes. The MZ-2361 from Cricklewood never materialised so I used 2 x 1N4007 in series. All seems to be ok only got no voltage gain putting 1vrms and getting 1 vrms out any ideas as to the cause ?

Just checking, and excuse me for asking, but make sure you replace the crowbar triac.

Good luck
