g max 100h (Waller)

[lowell]

Does anyone have a schematic for a Waller gmax 100h?

Anyone know the in/out z for a reverb tank for one of these? Is there a "probable" z for solid state vs tube driven tanks?

Is there a "probable" z for solid state vs tube driven tanks?

No, not really. Tubes may have a lowish impedance whereas solid-states may have a moderately high-ish impedance (something that can be easily driven directly with a transistor's collector, OpAmp or a pair of opAmps in parallel). Then again, many solid-state amps also employ a discrete push-pull output to drive the tank and can therefore easily do lower loads since the required output power is very low. You can't really tell, except by evaluating the circuit (output style, supply voltage, typical amplitude of the drive signal, etc.)

Anyone know the in/out z for a reverb tank for one of these?

I'm quite sure you wouldn't even ask unless you had already checked it and returned with no luck, but what the heck: Who's the manufacturer? Is there a type number or something? Does the manufacturer provide datasheets?

Have you tried contacting ISP Technologies (formerly Waller) in case they could help you.
