I'm still running a pair of Levinson ML-2's and I was wondering how much of your knowledge/intellect is there in those designs?
My Krell technician (former Goldmund engineer) prefers the ML-2's over the successors the No. 20 and 20.5. I never heard those latter ones so I can't concur.
Are the ML-2's mainly your brainchilds?

To tiefbassuebertr:
Congratulations with your nice MF preamp.
Did not know the English made such expensive gear.
Unfortunately that is not the preamp part from my own setup. I found the pictures on the web by chance.
Obviously there is no high circulation of this model.

Never liked the TKD's with there flimsy soldering lugs.
Just bought a Coherence One Series II so I'm back in P+G territory again with three of them lined up behind a faceplate.


Penny & Giles (Position Measurement and Control Hardware - Penny + Giles) are best known for their line of "industrial" controllers and linear faders. They also make a rotary fader (model RF15) which is the volume control you are asking about. It is built like the proverbial tank and looks like it would withstand a nuclear blast. I used these in my Deluxe Line Drive series of passive preamps back in the '80's, but gave them up after I found a part I liked better - the TKD conductive plastic pot. Like Penny & Giles, TKD makes a line of industrial-grade linear faders, but they also make rotary faders (potentiometers) and stepped-attenuators. These are excellent volume controls, but the stepped parts have gotten extremely expensive. The conductive plastic pot (CP2511) can be had from Michael Percy Audio (Michael Percy Audio Ordering Information) for $62.50, while the stepped-attenuator goes for around $250.

Best regards,

Best potentiometers without a doubt? Penny & Giles Model No. D460355/C recently resurrected. Heavier silver oxide and better machined tracks. "In the initial refit of a KRS-2, the Pot by Penny and Giles D19992 was found to be unbalanced between L+R at very low volumes, which was incredibly frustrating having waited six months for it. It turns out that the silver oxide manufacture was changed in the middle of the recession. After long discussion with Penny & Giles, an older type with higher tolerances was resurrected and produced... another three months... however the results are world class, Its model/ type D460355/C and the best available. Max differential between left and right tracks is specified at a maximum of 0.5dB, that -as it turns out- was the critical figure! The D19992 of the RF15 style was a max deviation of 2.5dB." TKD good but flimsy. The Model No. D460355/C is the best potentiometer out there, that is unless you go to rotary fixed resistors....and some other exotica that may well out live my grandchildren! If you do a google search for KRS-2 and find my posts on pinkfish media, an expansive conversation with penny and giles seeking the best potentiometer that they made for audio is peppered throughout that post, it took months and months to find this out. My ears concur.
