I feel a bit of an alien posting on this thread but here goes...
As I said on PFM, I owned a Series 4"PP" preamp back in the early nineties and very good it was too in sound. I DID get pee'd off with the volume contraols because this particular one mistracked badly at low levels (three o'clock on one and half three on the other for example) and I could never seem to get a satisfactory balance until the volume controls were over half way. I passed this example to a mate who had it stolen and a used replacement found by Tom (NAS) Fletcher wasn't as good sounding (dull and thick toned).
Bringing things up to date, I read about what turned out to be a fellow PFMer's experiences with this model and he got in touch and sold his sample to me

Since acquiring it, Glenn suggested I remove the yellow caps added by the previous owner, removing the resistors across the line input sockets (but not the output ones) and replacing the two huge blue supply caps for Dubilier ones of under half the capacity. The mains filter has been lobotomised if not actually removed as yet and the line stage valves have been replaced with long plate Mullards. The sound is wonderful, if not quite as clear as the newer preamps he's done.
As for the volume controls, as you can see, this era of preamp puts them at each end of the front panel - purely for styling as all the non phono wires are solid core and most run together down the left hand side of the case. Fortunately, the two pots fitted (500K ones it seems, not 1Meg as suggested) track quite well on this sample. By the way, no elastic band I've tried causes the two pots to move at the same rate! They ARE a pain to use, but if they are alongside each other, then I suspect it won't be a problem for most enthusiasts. I suggested the use of separate controls is more to do with component values and availabilty rather than a real problem with stereo controls per se. I mean the latest Alps pots (and I believe Noble too) have excellent low level tracking and are quite benign in performance I think....
What you lot have totally missed IMO is that NOONE has any qualms about the expected performance of these new products, nor the proposed prices. The ONLY comments made have been about the use of two volume controls! Not bad at all for a little manufacturer is it?
