Sherbourn 2/150 amp question.

[novisnick]

I need a little help friends. I own a pair of these amps but I do need the speaker connectors. I don’t remember what they’re called and I would like to locate 2 to 4 of them. They’ve been in storage (closet) for some time. They worked perfectly when I put them away and now I’ve found another use for them.

I believe I need the green connectors on the far right.
Not sure what the ones on the left are for.




Figured I’d show front and back for reference and a flashback!

Phoenix connectors. I have some to fit the inputs, but not the speaker outputs. Maybe check parts express, sweetwater, guitar center, etc.?

Good luck!

Thanks so much!

Found a connector. Good news, Bad news, I’m not experienced in making this connection.
I would like to use the Sherbourn if it has adequate power. The plare amp was 200 watts. I may need another amp or just purchase another sub, the Klipsch really do do a nice job of adding bass. It wasn’t enough to shake the room but its effects were adequate.

So how do I connect my AVR to this amp and then to this sub? Technical assistance needed please. 🤔

I certainly would need more info before making any suggestions, so far I’ve heard AVR, this Sherbourn, Subwoofer (w/plate amp?), assume there are other speakers involved? How do you envision this all goes together? What purpose does the Sherbourn serve?

Thanks for your questions. I was told that I should be able to use the Sherbourn amp in place of my burnt plate amp that powered a Klipsch sub. The AVR was feeding a signal via one of two sub out jacks.

The AVR has 7.2 out abilities and Im thinking that I use a sub out (signal) to the amp to drive the sub.
Possibly split the positive and negative of the sub out of the avr to the plate amp connectors that are will be  connected to the Sherbourn.

Thoughts? Ideas? HELP!
Forget about it?

Pretty sure you can just remove the rear plate amp, drill a small hole, just large enough to squeeze the positive and negative speaker wires from your amp outputs to the left and right speaker prongs on the woofer itself. Disconnect the plate amp wiring altogether. I added a nice 500 watt Dayton Audio amp the same way with a blown plate amp on my powered sub. After you have the wires to the woofer secure, you just need to put the plate amp back on, and put a small piece of putty or something around the remaining hole that you fed the wires through.

Look at my amp, how do I connect the AVR to my amp?

I would think you could just run the preout from your preamp or AVR to one of the inputs on the Sherbourn, the same way you would if you were using it as an external amp for speakers.

The Sherbourn has a left and right rca input while the AVR has a single sub out rca.

Just use either the left or right, it looks to be able to bridge but which channels bridge ?

Use something like this Nick. Rca out to Phoenix connectors.

Actually, disregard this. Connect rca to both reds on the inputs, select Bridge mode and connect to speaker one per the schematic.

I found this.

adaboy I’ve got it. After digging into my “Stuff I may need someday” box I found the connector I need. Now I’ll bridge the amp and run wires to both positive and negative posts of the sub driver via Phoenix connector.
Thanks to all! I’ll report back as to whether or not the amp has enough juice for the sub.
