Hi
I have a Prince Piggy-2 PS200R amp that has the most pitiful reverb ever. It sounds like someone throwing a metal pipe down the stairwell of a block of flats! I was wondering if replacing the reverb tank with an Accutronics would improve this situation? I realise the tank is not the only factor, but it's the main one. I will also point out that i would be putting the new tank in the base of the amp cabinet.
As you can see from the picture below, the tank it'self is a ridiculous (one spring) 2" square emarrassment to audio electronics!
I'm familiar with the concept of matching input and output impedances from other similar discussions on other boards, but how close do they have to be?
The measurement for the input is 208 ohms and the output resistance seems to fluctuate between 214 and 330 ohms depending on whether the amp is switched on or off while measuring. I am measuring where the wires from the PCB are soldered to the lugs on the input and output, as this reverb tank does not have those RCA type connections, it's all soldered.
I have looked on the accutronics website, and while i could get a match for input resistance, the output resistance is quite a difference on any of the models. Failing that, could the pcb component values be altered to accept the different impedence from the accutronics tank?
Any advice or comments greatly appreciated! More detailed photos on request.
