Dear Sunn Bretheren,
I received notice yesterday from AEC (Antique Electronic Supply) that they now carry several several replacement parts for Sunn amps.
This includes Sunn tolex and 1st generation Sunn grille cloth ...both unobtanium for decades. I suspect that these parts are being reproduced by the new owners of Sunn.
Note that the numbered Rogan 155 knobs offered by AEC are not exactly correct for the original 1960's - 1970's Sunn tube amps. The font used on these knobs are "square-sholdered" .... correct for old Music Man amps, but not Sunn.
Fortunately for me, I have a stash of Fender-era Sunn tolex (purchased from Conrad Sundholm a decade ago), 2nd generation grille cloth (purchased from the original manufacturer) and the correct 155 Rogan knobs (with the "round-sholdered" numbers).
I hope this info is of use!
No affiliation with Sunn. Just an old Sunn collector / amp tech.
