Adding speakers

[grizzlydude]

How would one go about adding a few wall speakers to a shp1 amplifier? Is it possiable to add speakers that are not seeburg? And if so what ohms would they have to be ?

The reason I'm asking is it's very hard to find seeburg speakers and if you do find some they cost a fortune.

Grizzled one, you can use any speaker you like, but some points:

-If you are using standard 4-8-16 ohm speakers connected to the wattage taps on the amp, bear in-mind that you'll be connecting to an amp that rates the watts into a 5 ohm load.

-If using 8 ohm speakers the watts will be approx half that claimed by the individual taps.  16 Ohm loads will be a 1/4th of that rating.

-Actual power delivered by the amp is NOT "100 w/ch" -it is actually more like 32-35 w/ch with both channels driven. --Use efficient speakers-- if you want loud levels.

- Avoid over loading the amp. Calculate the total loads taking into account both machine speakers and the load represented by the externals.

-Additionally, the amp should be biased  low so that it idles cool at the heatsinks and the main fuse should be no more than 2amp/slow (I use use 1-1/2 amp).

There is no such thing as "Seeburg speakers"--Seeburg purchased speakers (either made to Seeburg's specs. , or that match them), from various makers, and installed them into cabinets, which carried the Seeburg name/logo on them.
The addition of speakers is explained very well in the "Installation and Operation" (I & O)manual that came with every model phono--read it !

Yea I read it Ron , but I did not know that seeburg did not make there own speakers so thank u to Ron, and rob for the answers
