I am looking at a solid state Traynor YVM-3 PA 4-channel head. Can't have much power at all with 2- 2n3055 output resistors. I am getting rid of it. Can't imagine it being worth more than $25 and slow at that price. But, there is a nice working Accutronics short reverb tank in it. The first number is "1" rather than 4, 8 or 9. Does anyone know what the "1" stands for? I am just curious. The rest of the numbers/letters make sense. The reverb tank is dated 1975. My inclination is to keep the tank and toss the head.

DIGIT #1 - REVERB TYPE---------1 = Type 1
DIGIT #2 - INPUT IMPEDANCE----F = 1475 Ohm
DIGIT #3 - OUTPUT IMPEDANCE--B = 2250 Ohm
DIGIT #4 - DECAY TIME----------2 = Medium (1.75 to 3.0 sec)
DIGIT #5 - CONNECTORS---------B = Input Grounded / Output Insulated
DIGIT #6 - LOCKING DEVICES-----1 = No Lock
DIGIT #7 - MOUNTING PLANE-----B = Horizontal Open Side Down
It could be turned into a stand alone reverb unit but possibly now the schematic
of the reverb area is a bit basic compared to some modern designsAttached FilesComment

The first digit is the size and shape of the unit.Education is what you're left with after you have forgotten what you have learned.Comment
