If anyone has a Fisher Spacexpander reverb out there that works, could someone please tell me what the specs are for the transducers on the spring tank? I have an original Fisher spring tank, the transducers need to be replaced, but they are not marked, and this info is not in the schematics. I contacted the "Fisher Doctor" in New York, and he has no idea. I know that some Hammond tanks will work with the preamp, and those are usually marked. Any help will be much appreciated, so I can get my spacexpander up and running again. Thanks so much.

Well, Accutronics make hammond type 4 spring tanks (which is what the spacexpander tank is - I think Spacexpander just put their stamp on it - mine is orginal and it has the Spacexpander logo on the outside but the inside has a plate on it saying made by Hammond, Type IV))apparently to the same design as has always been used.

I think Accutronics are based in the States, but you may have a distributor in your country. The tanks are not expensive, there is a site selling type IV's for £28 (UK sterling) in the UK. I'm not sure if the input and output ohmages are a a match for the Xpander original tank, but I presume they are. I was thinking of getting one myself, because although my tank seems in full condition, I'm wondering if a new one would improve the sound.

Thank you so much. There wouldn't happen to be any code numbers on your spring tank, would there? The first would be 4, and the 3rd character, either A (500ohms),B(2250), or C(10K), corresponds to the output impedence. This is what I need. If not, at least you've helped me narrow it down to 3 possibilities.

1122-6142 and A 846-109A are the two sets of numbers stamped on it, but I don't think that conforms to what you are looking for.

Thanks so much for all the help! The two numbers you gave me must be some Hammond numbers, because they don't correspond to the standard numbering system for spring tanks. However, I was able to determine from the fact of it being a type IV that the output impedence is 10K. I was able to get the proper transducer and now my Fisher rocks again!!! If you plan on getting another tank, make sure you get the right impedence, because there are several type IV's. I don't know what the input impedence is though, I wasn't having trouble with that. Again, thanks so much for the help - DubSiren (The only Dub Chick in my town!)

I e-mail Cal Shuett, from SEPI-GROUP which makes Accutronics spring tanks, and here is what he said:

"My records show Fisher p/n A846-109A used a Gibbs model L, which is an Accutronics model number 4FB2B2C. This model can still be manufactured, however it will not have the clamp as the original had."
