It depends on the year. The early silver faces are still the black face circuit. They changed more and more as the years went on.sesroh said:anyone have this done? I'm wondering how much it costs to be done.
edit: I'm thinking of having a super reverb blackfaced but it already sounds great
Mid to late probably. You'll need to find out the exact year before someone can get a little more exact on a price. Write down the numbers on the transformers, they'll date the amp for you.sesroh said:all i know is that the amp does have a master volume and pull boost control. I have no idea what year. Im assuming mid seventies
If you like the sound of it then that's the most important thing!:food-smiley-004:sesroh said:it is the later 70 watt version. i doubt i want it blackfaced. i already like the sound of it.
Fender jacks are a bit tricky, in case you hadn't run across this before. The ext jack is wired as a shorting jack to put the extension in series with the main jack.sesroh said:i just found out that the extension speaker input is disconnected or something which is a little annoying because even if it's not neccesary, i like to be able to use a cab if i choose to. might have that looked at. same with the pull boost(which is some what good that it's disconnected). im pretty sure a few other things have been done to the amp too.
Haven't had my coffee yet so I'm probably missing something but are you talking about running an OT designed to deliver to a 2 ohm load into a speaker cab running 8 ohms?peter benn said:Careful here, Sesroh. The Super Reverb is the poster child for ext. cabinet impedance mismatches because of its 2 ohm output transformer (2 ohm parallel with 4 or 8 ohm ext. cabinet makes the amp "see" less than 2 ohms, thus approaching an open short).
From Gerald Weber, "A Desktop Reference of Hip Vintage Guitar Amps," page 212:
"....I would never use the 'ext. speaker' jack on a Super Reverb without rewiring the stock 2 ohm load (four 8 ohm speakers in parallel equals 2 ohms) to an 8 ohm load (series parallel or parallel series)."
And from page 210:
"....Series parallel.... more branch inductance and therefore will have less high end, better low end, and an overall crunchier tone.... wire two speakers is series and the other two speakers in series... Next wire one set in parallel with the other set... Impedance is 8 ohms."
"....Parallel series.... less branch inductance and therefore will have better clarity in the high end, a little less low end and an overall cleaner tone.... wire two speakers in parallel and the other two speakers in parallel.... Next wire one set in series with the other set.... Impedance is 8 ohms."
