I'm aware of the Carmen Ghia and the Tone King Meteor II from using the search function. What other amps are out there that are 2xel84 and do not have a master volume? I prefer PTP wiring, but if it does have a circuit board in it, the jacks and tube-sockets cannot be soldered to the board. There are so many amps and builders to research... I need to shorten the list.
