Sounds fine, truly LOTS of FUN to hear. Its for my ALTEC VOTT A7-800s at home ( 515Bs and 802Ds) .

Hi Jeff,
Great to see someone taking their paradigm as far as they can - it takes commitment and time. Kudos
Bet it sounds great.
Cheers,

First rate Jeff!!! Freakin killer!!!
I am looking forward to hearing your system with your new amp :)

Really beautiful work. My hat is off.
I like the blue chassis.
Sad to think the best part is hidden from view. Nice work!
+1. Very nicely done, Jeff. Congratulations.

One wonders how many amplifiers Mr. Medwin has made in the many years he has been a full fledged audio kook? I get tired just thinking of how much work he has done.
With great appreciation for the dedicated audio tinkerer, where the next step always begins - from those unafraid to TRY something.
You would never catch me using film caps there.It's lytics all the way for me.hahahaha..Anyway,gorgeous work but I want to ask you,what are those big caps with a bolt on them that almost look like a giant feed thru cap? What value are they or might they be a torroid choke maybe?

It is similar to a Clarity Cap DTAC MKP. Look up Humble Homemade HiFi's review of said Clarity DTAC cap, since they gave it a " 10 " rating.Mine are 5 uF, rated for 64 AMPERES Irms., and about 1.3 milli Ohm ESR at 100 KHZ.
I am using the two large round caps as a first bypass of the 15 uF WIMA DC LINK, across C1 - and also for the first bypass value across the WIMA DC LINK in the C2 position. C1 and C2 capacitor banks are for the B+ powering the Type 45 output's stage, as in L1/C1/L2/C2. It has a Low Stored Energy Supply ( LSES ), chokes are only 10 Ohms and 8 Ohms respectively in DCR, under two pounds in weight.
Amp's B+ and ground wiring is double 12 AWG, so it is effectively 9 AWG. Think of keeping intact "instantaneous peak currents" on music playback. What does it take to have the amplifier NOT to clip them off, and be M.I.A., lost in the amp ??
Sonically, to my ear, the large round "bypass" cap plays back ALL the voices of a large male chorus properly, you sense the men singing in a group individually " from the floor up", which I CAN NOT get any amp to do, any other way.
Fun capacitor to hear. Its grossly big. It also requires very thoughtful terminations on either side, to sound its best. Fun stuff.
