TrueTone amp schematics/info?

[tubeswell]

I have acquired a 'blank'* Sheldon Amps TrueTone head chassis with front and back panel markings (in white) screened onto a blue background. I am curious to know what amp this comes from (if anyone can help with this please?).

The control panel markings are Input, Vol, Compass, High, Middle, Low, Special Sauce, Freeze, Master and some on-off/stdby switch holes and a lamp hole, and the back panel has holes for a Mains voltage selector, mains and HT fuses, Triode/pentode (switch?), Impedance selector, 2 x speaker jack holes and Bias TPs and "Range" and (Hum?)"Balance" TPs and a footswitch jack hole.
On top, there are holes for what looks like 4 x octal and 3 x noval sockets as well as PT and OT mounting holes for upright (X mount) xformers.
Anyone got any idea what True Tone head chassis this comes from? and where I might get a schematic or some info on it please?

* there is no serial # stamped on the back panel (altho' there is evidently a space for such when the time comes)
TIA

(PS Edit - I think I found the 'amp' - now to find a scheme for it - http://www.sheldonamps.com/truetone/tt1.php )

Another little chapter in this story

I got a reply from Mark @ Sheldon saying that they would provide the TT1 schematic and layout to me if I provided a signed disclaimer saying I wouldn't claim any such amp as I may build with that chassis as originating from Sheldon, which I duly did. Time will tell whether he actually sends it to me I guess. And I promised to keep the schematic a secret (sorry folks).

Nice graphics and design.
I had imagined it was another wonderful product from those weird ANZacs, but it claims to come "from the heart of UK"
Oh well !!
Do not even begin to imagine what Compass and Freeze would do.
Can't complain about Special Sauce because I'm guilty of labelling one control "Polenta" (Italian cornmeal porridge, usually with meat sauce and lots of cheese, very tasty), for the very good reason that that was an accurate description of what it did to the guitar sound, according to Musicians
Good luck with the build.

Well 'compass' is just a fancy label for a one-knob tone control somewhere between V1a and V1b I guess, and I gather 'Freeze' is some kind of post PI tone control between the two sides of the output stage (to introduce 'ice pick' tones??), while I suppose 'special sauce' is a TS lift/raw control. All purely guesswork on my part I hasten to add (schematic is yet to be delivered)

Thanks.
Hope someday you will post some MP3 and gutshots (no schematics of course)
Good luck.
