voltage regulator valves (Read 2260 times)

Rensselaer Verified Member Offline Posts: 12	voltage regulator valves 01/24/24 at 13:20:04 I am wondering if anyone can tell me how each voltage regulator set (OC2, OB2, OA2) will affect the final sound of the Sarah (SEWE300B), and if the purchaser can order a set of all three to try out for themselves?

Ren, I find the effects to depend so much on the power coming into the amp, the power cord, and the entire tube complement that it is hard to make a general statement. In the SEWE300B I rotated the three different tube types and different brands of the tube types, and decided for MY system using three 75C1 (which is a variant of the OC2, a shorter tube with a dark lining) to be the best--it gave the most power as well as a focus that was not hard or sharp, or too soft. When I had the SE84UFO3 monoblocks I found 0D3 to work best for the output tubes and 75C1 for the input tubes. Others made other choices.

You could make a query to Sarah or Veronica to see whether they could sell you three tube types in sets, or I have always easily found examples on ebay.

They should be here by the end of February….coming from Serbia. I was looking to refresh my OC2 tubes anyway, so I’d figured I would give them a try. Do you have any experience with the Phillips? Dom

I don't think you can go wrong with these tubes. I'll be interested to hear what you think of a pair in action!
