Ages and ages ago, a coworker brought me his Fender Frontman Reverb amp saying it didn’t work. He had a second one that did work, so there wasn’t any rush to get it working, so I took the unit home, and went to work on it. Disassembly was easy enough, and finding the schematics showed that the unit was identical to the Fender Frontman 15R, which has schematics (in the service manual) here. The US Fender site SAYS it has schematics for the 15G-15R, but only the 15G is shown, meaning the whole reverb section is left out. =/
