carbon dating exponential process - Dating a fender champ amp

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.

Our Buyer’s guide to vintage Fender amps explains in detail how you can date your amp by looking at serial numbers, tube charts, transformer codes, speaker codes, Fender logo, etc.

Neither the date nor the value can be determined from the serial number.

Fender’s amps, unlike their guitars, are not tracked by the serial number.

That Music Master Bass amp or Silverface Champ that you could have bought all day for 50 bucks as recently as 2 years ago can run as high as 350-400 on ebay now.

Though, hopefully no one will bid on those that are that high. But, they are still available at killer prices, if for no other reason, there are many of them still available..a silverfaced amp was passed over in the 80's and 90's by someone that HAD to have a tweed or blackfaced one.

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.

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.

You may compare these with your own speakers to determine what you have.
