The Audio Fedirection guy got a new camera? I bet he did. Anyhow, the pictures are courtesy of Audio Fedirection blog.

As I said above - I was as queries to have a preview of that ML3 amp as I was wondering about the plate voltage on that GM70. I do not see anything objective on the pictures, so the only circumstantial evidences might be observed.
OK, the first oil cap is 2000V rated, it OK, they all this way. There is nothing “investigative” in the power supply beside the fact that Lamm left on of the major ingredients of his amplifier not installed but to let it to sit next to the amplifier on the right. The connector cable between the amp and PS looks small to care the GM70 filaments along with the rest of the filaments + volute for 2 plates, including the high voltage for GM70 plate. In the amplifier itself there re also some questions. Large caps in PS + large amount of rectifiers and looks like low-voltage connection cord? Would it mean the Lamm went for symmetric power supply (with vantage doubler) and he then surmised the lower voltage shoulders right before the GM70 plate? For instance if he has two by $500, oops sorry by 500V, then he might get 1000V… It is not enough for GM70 to sound good. Still if it so, then why he need to build up so powerful buffer in the drive stage if he has alredy1000V and might stay in A1 with his 32W? I do not know...
Anyhow, if any of you learn about the actual plate voltage on this amp then let me know. If is turn out to be 800V then it would be renamed from Lamm ML3 to deHavilland ML2805. The deHavilland because there are plenty of mediocre sounding low voltage GM70 amps out there and the 2805 is because it would need to keep some “Lamm’s touch”…. (2805 = ML3 x 935)
Also, I was wrong in my assumption in the post above that Vladimir used feedback as substitution to the transformer tabs. The amp looks like has a number of tabs for different impedance matching Lamm’s 3 settings of feedback apparently is a derivation of his big “Theory of Human Hearing”. I think Vladimir invented his theory by looking at the map of Saudi Arabia and considered that if David Wilson managed to sell hundreds speakers in there then they all need his new deHavilland ML2805…
In the end it looks like it is VERY-VERY simple amplifier, regardless of the price. The GM70 with it 1000K plate impedance would require a complicate transformer (not to mention the voltage) but it is still NOT NECESSARY as the entire idea of a full-range operating SET become BOGUS for even $5000 as a par of DSETs with cost over $5000 ABSENTLY AND CERTAINLY OVER-PERFORMS any same full-range operating SET.
