There is a Red Frankie head on eBay that is in really nice shape, but it's different than any Frankie head that I've ever seen. The front panel is marked By Ross Mfg. The two channels are marked Guitar and Bass and the two front panel fuses are rated 2 Amp for the ac line and 4 Amp for the speaker.
Most Frankie heads are marked with high and low inputs and have 3 Amp ac fuses and 5 Amp speaker fuses.
Another thing is that the power transistors on the back panel look like they are Germanium transistor rather than the normal Silicon types. In fact they look a lot like the outputs from the original Lot-O-Tone heads.
Anybody here know anything about these heads?
I can't get the link to work, but here the address.
