So, here I am, writing about the history of some old gear, the Silverface Fender.
I also have a small amount of knowledge of and experience in working on tube amps.
I recently purchased a 1972 Silverface Champ for 40 bucks.
I am not an expert on amps, Fender amps, or Silverface Fender amps. I am merely someone that loves old gear, appreciates Silverface amps, loves to write, and loves history.
Fender has used only a handful of different speaker types over the years.
The format may look like this: 220 637 Here the number 220 designates the speaker as a Jensen, and 637 indicates a production date of the 37th week of 1956 or 1966.
by Frank Stroupe ***WARNING-There are voltages inside of a tube guitar amp that can KILL you.
There are components in the amp that hold live current long after the amplifier is unplugged.
I use this before buying a amp always-check all four transformers-will tell you if there has been problems along the way. On the bottom lower corner of the grill cloth was/is a 1×2 inch “JBL” plastic logo that Fender attached.
By 1968 deluxes usually left with CTS/EMINANCE speakers (Jensen had closed down) Once in awhile you can see the EIA code, CTS-starts with a #137-sometimes these are under the doughnut fender speaker label.
