FDP Forum / Fender Amps: Vintage (before 1985) / 1966 Super Reverb, The Standby Switch



Sep 18th, 2017 06:44 AM   Edit   Profile  

Hi again
Another Super Reverb question....
When was the standby switch introduced. Mine doesn't have one but I have seen another post where the owner has trouble with his. Both amps are supposedly from 1966.....Mine was originally sold in Denmark.

This ought to be interesting, I've never seen a SR without a standby switch, Blackfave or Silverface.

Back panel printed in English?... Appears Hagstrom would modify export models for their market.

Scroll down the linked page a little way...

If these amps were modified for the European market, how would that have anything to do with eliminating a standby switch. The switch is used to warm the tubes before they are slammed with higher voltage. Wouldn't you need to do this regardless of what type of voltage suppliy you use?

I think Fender used it as a convenience feature from the beginning for players simply wanting to mute their amps during a break. Leo was famous for giving working musicians what they wanted. Most tube rectified guitar amps don't really need them for the purpose of protecting power tubes anyway. By the time the GZ34 conducts high voltage, the 6L6GCs are heated and ready for trans-conductance.

Not so with SS rectified guitar amps - that's where you'll get an immediate surge of high voltage on your 6L6GCs when you power on. But a '66 Super Reverb is tube-rectified anyway.

I wonder ... Maybe in '66 CBS thought it would reduce cost on European models? What's the cost of a SPST switch and 12" of wire? ... seems silly.

Would seem more costly to create a Europe-only chassis and face-plate without the switch. Who knows? I'd guess it was early CBS decision to keep costs down. Others may have more accurate historic data.

At the end of the day, you don't need one in that amp anyway. One less part to fail and replace in a 50-year old amplifier.

Just my 2 cents worth ...
