Often I am asked which amplifiers will interchange. Below is a list of direct interchange by amp model, but there may be a slight difference in sound quality. ********************************************************************************* AMI: The C, D, and E amps will interchange with no alterations. The Continental through K mono amps are all the same as well as the Stereo amps from the same machines.
Seeburg: Field coil type Seeburg: MRA-1 MRA-2 MRA-3 MRA-4 Permanent magnet type Seeburg: MRA-5 HFMA-1 HFMA-2
Stereo tube type Seeburg: SHFA-1 & SHFA-2 will interchange SHFA-3, SHFA-4, SHFA-5 will interchange, but 5 is the only amp with a connector for the side speakers found on the DS.
Wurlitzer: You are really limited here to a few interchanges: Any 501 and 503 will swap. In most cases, they will also work in a 700.
Rockola: I'll have to do some research on Rockola amps as far as interchange data is concerned, this info will appear in a later column. The 1422 and 1426 amps are the same, the 1428 is unique. NOTE: You will occasionally find a Seeburg amp in an AMI, etc. but these swaps are difficult to do, and generally don't work well. |
