Well I’ve not had too many sherbets today.
I’d been using a pair of 10K TOCOS pots borrowed off our Ant as volume left and right controls. Nice pots, Anyway I found, while tidying up the hobby room, a 250K stereo TOCOS pot I bought years ago, when Nick Lucas first started stocking them; so this evening I fitted said 250K pot to the front end. I didn’t think this SEOTL could get much better, but it has improved again.
The top end has found more extension from somewhere and the amount of midrange magic has taken another step up in quality. Sometimes OTLs can be a little bit ethereal and this one is no exception, but the presentation with the 250K pot, is a lot more grounded and confident. I have a wider, finer range of volume adjustment too, which is what you’d expect, so I’m not confined to the first 90 degrees of turn from zero volume. Needless to say, I can now return the 10K pots their rightful owner.
I have a pair of 250K, Allen Bradley mono pots: those that I used on that lovely pair of 2A3 monoblocks I built around 10 years ago. These were something special if I remember rightly, but alas, the shafts are now too short to allow the knobs to be fitted; pity that. Never mind, the OTL is singing very nicely thank you, and is once again, out in front of my solid state NVA clone.
