That being said, the ADS 910's which are 4 ohm, sounded great with the Scott. The only complaint was @ 35 wpc, it ran out of steam pretty quickly with them. Isn't that an LK-48 / 299B? I have had both the LK-72 / 299D and the LK-48 / 299B in the stable in the past. Unless those are 6GM5's in octal adapters, they look like 7189's or am I mistaken? Wouldn't be the first time. Other than the finals, the two look pretty much the same from the rear. When you replaced the selenium rectifier with a silicon bridge what resistance did you end up adding to match up the expected voltage? As you may guess, I love working on paleolithic Scott gear.....

LouB Posted October 21, 2016 Report Share Posted October 21, 2016 Same here, I started with a 22 ohm and ended up with a 33. Link to comment Share on other sites More sharing options...
Bijan Posted November 2, 2016 Report Share Posted November 2, 2016 I look forward to getting my 20xw Sherwood back from my tech and running some 17s with it! I have some 5s as well, but I thing the 17's will be just fine. Link to comment Share on other sites More sharing options...
