L W Erath Amplifier?

Tex

Has anybody ever heard of this? I have learned enough to know that it is from the 60's and that it was made to fit in the back of Erath speakers. I also know that it is solid state and 60wpc. I hooked it up and it seems to work perfectly. Just looking for any information on this or their speakers. thanks.

"Erath's feedback control unit was in the speaker box next to the crossover network. That meant that the negative feedback lines from the amp's output stage had to be "clipped" and extended out to the speaker using some 6 conductor shielded Belden cable. 2 conductors for the regular voice coil audio, and 4 conductors for feedback 2 incoming and 2 outgoing. This was all connected using 6 conductor TRW/Cinch-Jones "jones Plugs" which made it all very convenient and inexpensive.

As you can imagine, some amplifiers didn't seem to care about having 15 or so db of their negative feed-back 'whacked away' at the low frequencies and some didn't like it all. In Erath's defense, I will say that he recognized and dealt with this problem in a very honorable way and would openly tell prospective buyers which amplifiers worked well and which ones didn't. Erath made a 60 watt per channel solid state amp that nestled right into a cavity that was in the rear of the model 1 box and was isolated from the inside of the box. This one was so stable it would allow far more feedback to be removed than most commercially available amplifiers at the time."

Thanks for the information. I guess the amp is suitable with any speakers but I think I would like to find some of the original speakers and cables it was made for to see how they sound. If it is worth anything it might just wind up on ebay. It was a garage sale find and looked to be old but very high quality.
