cyclopia: Sweet! I know more work went into that than meets the eye and bet it does sound nice.

Thank you seaside~ and thanks for other comments of all..

Sorry for my short english so... i expect seaside to reply for any other questions~

Because he has more knowledge about this amp, a kind of MHHA.

I'm just only able to copy of other member's works in HAS.
The voltage converter come out from Ryanjun's idea~~.

About the cost....hmmm...I can't remember exactly, but about $25 paid for case work.

That's very cheap for the case work, and it looks superb!

Great work cyclopia

I finished my first CMOY:

The guts, nasty I know but it is my first amp.

I used my favorite CMOY layout, input/output with switch in between and the LED on the side.

My 3rd amp, a Millett Hybrid. Finished some weeks ago.
[size=xx-small]Lately I took off those ugly bolts from the Neutrik combo connector (hp-out) and replaced them with fancy screws.[/size]

Potentiometer is a 22-step "fake RK-27".
All electrolytics are Sanyo MV-AX series.
All film caps are Evox Rifa PHE 426 series.
Resistors are standard (generic) blue ones.
Just had to put some blue leds under the tubes...

The amplifier board is fully detachable.
Equipped with a TREAD and a Diamond Buffer.
Power comes from a wallwart.

The (4 pole 3 position) rotary switch on the right is the power switch. The red LED is connected to Tread and the green to the amp. When you turn the knob one step clockwise the Tread goes on and the red led turns on. When you turn once more the amp goes on as well (and both leds are on).

Of course, this function is practically useless but I wanted to make it. I'm very fond of driving so you could consider it as a ignition key in a car

[size=xx-small]Off, power on, engine on[/size]

I had a transparent plastic top on it but decided to remove it. After some hours of use I removed the top and measured DB's (bias)voltage. It was 100mV

I had used default 2R2 resistors. Optimal would be 44mV and maximum 66mV. Luckily the transistors didn't fry...

Some Pictures (had to include the compulsory night shot):

[size=xx-small]Soon for sale...[/size]

Wow! Great work! How does it sound?

 

[bhjazz]

Cyclopia - did you do your own acrylic cutting? Between that and the silkscreening, it looks very professional. Beautiful work!

Tsappis - great work as well. That case is a great size for the project!

 

[Polaris111688]

Woah... That's a pretty Millett. I'll have pictures soon of a new project I'm working on. PPAv2 amp with STEPS, Epsilon 12 protection circuit, and a VU meter board I designed (based off of a project online. I worked off of the schematic).

 

[Dave_M]

Tsappis, that case is very nice! Is that a hifi2000 model from audiokit.it?

 

[bperboy]

Here's my discrete Diamond Buffer that I finished today for my Millett, just now got around to it!

EDIT: That's right, I've got the dDB, Millett, and a Tangent Modified Linkwitz PCB all crammed into that little Hammond case!

 

[mb3k]

That's some serious crammage.
How do you like the sound through the Linkwitz? I personally find it dulling to the music, but I'm interested in your opinions.

 

[bperboy]

I don't know that I can really tell the really subtle differences between these small system changes, as I can hardly tell the difference between my M3 and Millett, but, I feel that I could probably have gone without including the crossfeed and not miss anything. I don't want to take it out now, because it would be far too much work!

EDIT: I actually ended up flipping the crossfeed upside down to get it in the case, I had to remove one of the tube rings temporarily to get the top on over all that stuff!

 

[Tsappis]

Thank you all for the compliments. I was thinking of getting some Black Gates to replace current capacitors...

Sounds good, especially with some 12FK6s. I very much prefer those over 12AE6s. Unfortunately I couldn't get any 12FM6s but I doubt they would have been better than those 12FK6s.

I doubt. It's a Teko Dissipator series bought from a local distributor. I really recommend this case. It's a quality product and was very easy to work with.

Very nice build. What are the approximate case dimensions?
