I have 2 superphon revelation dual mono pre-amps, circa 1986,
which have served quite well for all these years. Serial numbers
are 01270 DM and 01291 DM. I'd like to know of any suggestions about modifications of this preamp, given it is now
over 20 years old. BTW I have not had any problems with the pots or mute switch on either unit.

I did replace what I believe is C10,11,12 and 13 with 100uF 50v
blackgates. I use it mostly for playing lps, so anything to enhance the phono section would be great.

I also have two DM 200s....any suggestions for those would also be appreciated. or maybe that should be another thread..

Maybe if I get lucky the guy who designed these will answer :)
