Thanks guys! so far I have spent around $600 in parts. My last update was the potentiometer, now it has a TDK. I know with that kind of money I could buy a nice commercial amp, but this diy amp kicked my Bryston's B60 butts that is over $2k and beside it is unique lol!!! it is a small passive integrated amp 2 1/2 H X 8 W X 12 D. The amp kits are the M400 take a look the specifications:http://hdamp.com/M400.htmlMake it simple...Make it better!

Awesome work! DIY is a blast, and I cannot wait to take on my next project. Thinking I might go for a preamp next time.Thanks guys! so far I have spent around $600 in parts.

Thanks! I would strongly recommend you to use TDK in your pre-amp. I did try Alps, Noble and TDK potentiometers and the TDK are way,way better than Alps and a step above of Noble potentiometers. They cost more money ,but it is worthy the extra $...Make it simple...Make it better! -
The ribbon SDA will require a massive amount of skills I do not currently possess. I am finding the dipole designs to already have much of the same characteristics as SDA's have anyway, at least to my feeble ears.The Gear...

I will take the tip to heart Lanchile... I am looking at throwing a grand worth of tubes at my Sunfire to see if I can wake it up first, but from what I have been reading, the amps mine are based off of tend to roll off on the highs, Don't know why that is, but I will be checking with Bob to see what he says.The Gear...

Goldpoint is another great attenuator.
Did you use carbon pots in your amps like Bob does? If so, bypass them."He who fights with monsters should look to it that he himself does not become a monster. And when you gaze long into an abyss the abyss also gazes into you." Friedrich Nietzsche -
I did not put in volume attenuators on my amps. I saw no need for them so long as I have balance controls on the pre.The Gear...

I've got an interesting piece of equipment, pictures of which I want to post on this thread as soon as I can dig it out of the closet and take the photos.
A little tease: Perhaps an iPod precursor?
More to come later; I hope later today, but maybe tomorrow.
Cheers!Family Room, Innuos Statement streamer (Roon Core) with Morrow Audio USB cable to McIntosh MC 2700 pre with DC2 Digital Audio Module; AQ Sky XLRs to CAT 600.2 dualmono amp, Morrow Elite Speaker Cables to NOLA Baby Grand Reference Gold 3 speakers. Power source for all components: Silver Circle Audio Pure Power One with dedicated 20 amp circuit to main panel.

Good music, a good source, and good power can make SDA's sing. Tubes make them dance. -

Love the "stealth" wiring around the toroidal. What kind of amp is that?

Balanced Audio Technology 200-VK; 100wpc at 8 ohms, 200wpc at 4 ohms high bias class A/AB (the amp bench tests at about 75% more than the rated power specs :cheesygrin:). The gets a hot as many SS true class A amps I've owned, but it still sounds warm and detailed with much more power and punch. Despite the sparse look in the chassis, because of the transformer and heat-sinks, the amp still weighs about 65lbs. -
Krell KSL balanced pre amp with Krell MM/MC Phono Board. Primarily Roederstien EK caps and Sprague. I've seen later versions with all Sprague caps. A nice TKD volume control. The first two are Carl's pictures from when it was first sold.Salk SoundScape 8's * Audio Research Reference 3 * Bottlehead Eros Phono * Park's Audio Budgie SUT * Krell KSA-250 * Harmonic Technology Pro 9+ * Signature Series Sonore Music Server w/Deux PS * Roon * Gustard R26 DAC / Singxer SU-6 DDC * Heavy Plinth Lenco L75 Idler Drive * AA MG-1 Linear Air Bearing Arm * AT33PTG/II & Denon 103R * Richard Gray 600S * NHT B-12d subs * GIK Acoustic Treatments * Sennheiser HD650 *

Hey Rich!
I see that you have your tools out again! LOL! I took the first two pics, but the last two have your fingerprints on them.
What a fabulous preamp!Carl -
Hey Carl! Just a little bench check, pop the top, clean, run an EKG and check pulse.:cheesygrin:
Ed is trying to set me up with its old friend, the Krell-der KSA-250. Despite the age it is a very impressive pre amp and phono stage.Salk SoundScape 8's * Audio Research Reference 3 * Bottlehead Eros Phono * Park's Audio Budgie SUT * Krell KSA-250 * Harmonic Technology Pro 9+ * Signature Series Sonore Music Server w/Deux PS * Roon * Gustard R26 DAC / Singxer SU-6 DDC * Heavy Plinth Lenco L75 Idler Drive * AA MG-1 Linear Air Bearing Arm * AT33PTG/II & Denon 103R * Richard Gray 600S * NHT B-12d subs * GIK Acoustic Treatments * Sennheiser HD650 * -

Looks like they've beefed up their products a bit. Does this one have balance issues at low volumes like the original Nova?"He who fights with monsters should look to it that he himself does not become a monster.

Not that I have heard, and I keep the volume between 9 and 11 mostly. I know they changed the amps to IcePower for the new Nova and Grand Integrated, and a chip amp for the Decco, not sure what other changes were made.
Am looking at the new Nova now for the HT, torn between that and a W4S Mint. If I get it i'll be sure to pop the top and show the guts of that one to, though the only difference should be the amp. -
I'm currently using a Mint, it's a nice sounding unit and should be a step above the new Nova."He who fights with monsters should look to it that he himself does not become a monster. And when you gaze long into an abyss the abyss also gazes into you." Friedrich Nietzsche
