The Champ had only one power tube,and the power stage circuit is, typically, single-ended and class A.
Five watts and the simple toneful circuit allowed the Champ to be used easily and often in recording studios.
Since several models can share one chassis type (for example, the early brown 5G7 Bandmaster, 5G5 Pro and 5G12 Concert), this kind of interpretation is inaccurate.
Instead, there were approximately 2000 of these chasses produced, which then ended up as one of the three models in question.
Hi, Having some problems dating a Fender Twin Reverb silverface and would appreciate any info on dating I have extracted the following details from the the amp: Serial stamped on chassis 'F091028' then in ink below it '0804' Power supply 013830 EIA 606-013 CSA 827 Small transformer (tiny) 022927 EIA 606-022 Any info appreciated Cheers Harry If the amp is a 135-watt ultra-linear chassis with push-pull master-volume boost control, the tranny numbers indicate it was made in the spring of 1980, which I believe was the last year of production.
I have a silverface deluxe reverb I'm trying to find out what year it is.
Some things are very obvious such as non-original or reconed speakers, non-original transformers, replaced pots, re-tweed, re-tolex, re-grill, etc.
and these changes are often disclosed and of a non-malicious nature.

Examining the EIA manufacturers codes stamped on the amp's trannies is a more definitive method of determining the vintage (assuming the trannies are original to the amp).
It would be more accurate to say that approx 650 of each of these models were produced in ’60.
