For Sale: Bob's Devices Cinemag SKY 20 MC SUT, excellent!

[Unchilled]

Bob’ Devices: Sky 20 MC Step Up Transformer. I purchased this SUT on USAudiomart from the original owner -- he purchased from Bob in January 2017. Excellent condition + Clearly superior to the built-in Lundahl 9206 SUT's in my preamp. New $1250 -- asking $825 -- including shipping in U.S. from 90024 and PayPal fees. The SKY 20 is switchable for 1:10 (20dB gain) or 1:20 (26dB gain). There's also a switch to either lift ground or to connect chassis ground. Easy to install. Sound with a ZYX Airy 3 -- dynamic and detailed. The reviewers have loved this product.

Thank you Myles. Asking price now includes shipping in the U.S. and any PayPal fees.

I'm anticipating delivery of my updated FVP preamp -- includes an FET/6922 phono stage and 12AT7 line stage -- from Joe Rasmussen, the designer of the well-regarded JLTi solid state phono preamp. The FVP has facility for adjusting phono input impedance with parallel RCA loading plugs -- which I'll predict will suit my Sound-smith Sussurro very well.

Why don't you start a thread about FVP? I'd love to know more about the product!

Hi Myles,
When I've had a chance to listen to it (it's been out of the system for a few years), I will do so. Joe Rasmussen collaborated closely with the late Allen Wright. The pre-update version also used 6922's in its line stage. There's an old review in TNT -- www.tnt-audio.com/ampli/vse_fvp5a_e.html

l find it interesting that Joe has chosen to use the 12AT7, nominally a higher gain tube, in the linestage -- selected for musicality -- while sticking with the FET/6922 in the phono stage -- I don't pretend to understand electronics engineering.

many linestages use 12au7

IIRC the 12AT7 has considerably higher gain than the 12AU7. Not sure how it otherwise differs.

interested, if still available.
