| ISO Traynor YBA2 schematic, 5Y3 rectifier
I've got a YBA2 on the bench, this one has a 5Y3 rectifier and 6AV6 preamp tube (along with single 12AX7 and 6V6 pair). I can't seem to dig up any schematic for this amp that has the tube rectifier and odd preamp.
For now it plays, but its overly loud and abundant in low frequency. The 3-cap multi-section can isn't marked so I've got no idea what to swap in.
Voltages thus far:
B+: 350vdc
6v6 plates: 340vdc
6v6 screens: 320vdc
6AV6 plate supply: 305vdc (before 100K plate resistor)
12AX7 (phase inverter?) plates: 212vdc. |
