Fender Super 5G4

[angelodp]

here is the gut shot for this amp. have not been able to get a proper schematic for it? Its close to a 6G4 for not quite. Does anyone know what that domino ( I think cap ) thingy is please.

That is an old style mica capacitor.

I have an old Magnatone that's got a lot of those domino caps in it. I was told they are military grade caps and would probably outlive me. I've never taken one out of circuit to measure though.

What a beautiful amp you have there!

According to my interpretation of this page:
http://online.physics.uiuc.edu/courses/ ... n_Amp.html

a 5G4 is nothing more than a 6G4 made prior to 1960. I compared yours w/ the 6G4 layout from schematicheaven and it looks like a 6G4. Not able to compare component values though.

I've got a couple of amps w/ those domino-style caps and I think they look really cool. Unfortunately, you can't see them when the chassis is in the cab.

I've always really liked the brownface fenders. I think you've got an awesome amp there.

I did a quick search and found this

regarding the correct interpretation of "dominoes"

I remember seeing this info before in the ARRL Handbook (every "amateur engineer" should have one), but mine has apparently gone for a walk - or something

I happen to own an early 6G4 brown Super with a May '60 stamp on its tube chart. It most likely has the same specs as yours:
- Triad trannies (still the same type found in narrow panel tweed Supers)
- Astron caps
- tweed era brown grill cloth with yellow threads
- pink brown tolex
- unused 'Pulse' hole on back panel (or is yours wired to anthing?)
- better sounding, more open and crunchy circuit than the 6G4A (
- more standard sounding tremolo circuit, whereas the 6G4A-type is unsurpassed
- longer version, second generation dogbone handle
- tweed era style push-on tube shields
- volume control in standard position (has yours the odd position to the right of the bass and treble controls?)

Has yours P10Rs or P10Qs?

Regarding the model code: The 5 in 5G4 stand for 50ies, G might be for Generation and 4 is the specific amp model number, i.e. Super Amp here. Leo Fender had a reputation of absolutely hating to waste anthing, so odd specs are found all over the Fender poduction even up to the very late 60ies, when Leo had already left due to health problems.
