The Walnut Amp camp has sold.
-
As the title says, wife and I are having our first baby and that pushed me to finish all my partially completed projects to get rid of some parts I had on hand over the last 7 months! I have been building these items for fun and experience over the last 3 years and learned a lot. I recently started making my own custom logos to add some flair to the amps. If you do not like the look of an amp or want a special logo made separately, let me know and I can include so you can swap it out. I have listen to and enjoyed all of these pieces in my system, but realized it's time to let some of it go! I generally try to match up preamplifiers with amps and would offer discounts for multiple items being purchased. I am located in Houston but willing to ship. We can negotiate shipping if multiple items are purchased.
I can send more pictures, just PM me or message on this thread.

About to post some new gear I’ve completed and no longer need. Just need to put some finishing touches.

Sorry. I just sold them but I do have one very good stereo amp I built that I am about to post.

For sale is a completed class A Nelson Pass designed setup I put together with matching custom designed vinyl logos.
I built the Whammy and PSU but did not build the amps originally. I did, however, upgrade them and check all solder joints.Description of each piece is below:
- Whammy Headphone Amp/Preamp is a Class A preamp designed by Wayne Colburne at Pass Labs. High quality parts and includes Preamp outs and a switch to go between headphone and preamp out. This can easily run low to high impedance headphones and makes a great high gain preamp.
- Amp Camp Revision #1 monoblock amps. These are highly modified with upgraded schematic part changes discussed on DIYaudio forums, adjusted for 24V input, and have an upgraded PSU I built.
- ACA PSU includes a torroidal Antek transformer with 200va and 20V secondaries for a steady 24V power to the amps. The power filtering is a Cap Multiplier supply that is a huge improvement over the original 19V supplies and newer 24V supplies recommended by Nelson. The PSU connects to the amps with special Umbilical cords I created.
Amps put out 10 watts of SMOOTH Class A and would work well with any 90db and higher efficiency speakers, especially Klipsch. RCA input only to the preamp and only one input.
Any questions, just ask. I am only selling this setup as a set. Located in Houston, TX. I am asking $800 plus ship.

One more pair of these amps for sale. A friend I built these for traded up to a torroidal version I built for him. He had a carpenter design the faceplate out of Curly Maple to look similar to a Pass Amp and I installed them. These are beautiful.
Asking $650 and I’ll ship for free in the continental US. These are the same as the Walnut ones but don’t have the SMPS filter board.

Price dropped to $700 and will still ship for free within the US.

I am the original owner of this Don Sachs Linestage unit and paid $2800 for it. I ordered it from Don approximately 1.5 years ago and it has performed great ever since.
It was built in walnut, caps for 47k or higher impedance, XLR inputs, and has the WE6sn7 tubes and uses the 6BY5/6X5GT.
The only issues with this unit is the cabinet. When I received the unit from Don it was not double boxed so one back/top corner was slightly dented and there was a 1 inch scratch on the side. I couldn’t ship it back because of funds and timing (moving houses) so Don gave me $200 for my troubles.
I patched up the corner and thought about lightly sanding the scratch then re-sealing the wood but could never see the small damages while on my rack so I didn’t care to take the time. I considered adding some decorative corner brackets to the unit as well.
I am having my first child so selling this to help with funds. Asking $1800 and I will ship for free anywhere in the CONUS.
Any questions, just ask.

Still available. Pictures below of the newest black ones I built with Walnut faceplates.

Looking for a 10inch woofer for a KG 4.2. I believe it is the same woofer used by the 4.5 and 5.2. I see one on ebay for $100 after shipping, but hoping to find one cheaper.
Model number is K-1005-k.
Thanks!

Bump. These are still available.

Nice condition Marantz SR 7015. Comes with Audyssey microphone, remote, antennas, and power cable. There are some very small scratches on the top but hardly noticeable. The unit has been updated to the newest firmware.
Can ship to the continental US for no cost extra. Asking $1650 for a $2800 unit brand new. Shipping basically free!

Newly built Amp camps designed by Nelson Pass. I added power filtering boards for the 24V Meanwell Power supplies and upgraded parts changes that bring the amps to a new level! Can be run as monoblocks balanced XLR, bridged rca, or parallel rca up to 16 watts Class A per channel.
If you have questions, ask or PM me.

Agreed. Parallel sounds awesome. These amps are fun because you can use them so many different ways if you have monoblocks.
-
Also, I use the exact same 24V Meanwell power supply.

I buy the exact ACA boards from DiyAudio that’s in Nelson’s Amp Camp kits. What I do is upgrade the parts, modify the schematic based on recommendations from DiyAudio forums and my experiences, add filtering boards, and diy my own chassis.
The chassis from DiyAudio costs $150 and makes up almost 50% of the amp. I am able to source my heatsinks locally for cheap and get them cut to size so I can make a chassis for much cheaper.
-
Here are pics of another pair I built with black heatsinks and black bottom. I will be finishing them with tops this weekend and offering to finish them with a specific wood faceplate if someone wants to buy.
I have Zebrawood, Birdseye Maple, and Walnut available to use.
If I don’t have any takers I’m going to go Zebrawood but attempt to dye the wood darker.

Amps are still available. I am also building one more pair with black heatsinks, black top and bottom, and Zebraswood faceplates stained black if anyone has interest.

I'm interested. For clarification these are monoblocks and accept one XLR input to each monoblock?
Why two speaker terminals? Different impedance options or is that for RCA hookups and stereo amplification?
Do you accept PayPal? Will this be insured shipping?
Thanks
Jc
Yes I accept PayPal. Regarding insurance I didn’t have that included, but we can work something out.
-
Sorry everyone. Was on vacation and just returned.
To clarify, yes these have one xlr per amp so you can run them as xlr balanced.
The reason there are 4 speaker posts and 2 rca inputs (left and right) for each amp is because I built them exactly like Nelson Pass’ Amp camps from DiyAudio but with modifications.
$700 total. I’ll cover shipping within the continental US.-

Two Custom built Amp Camp ACA Class A monoblock amplifiers with a lot of upgrades and differences from Nelson's $350 kits on diyaudio.
- 24V Meanwell SMPS Power Supplies
- Birdseye Maple Faceplates
- Slightly larger heatsinks than the diyaudio amps
- XLR input and bridging switches
- upgraded interior parts included changes recommended by Tungstenaudio on diyaudio (smooths out top end, tightens bass, more dynamic)
- added Power Filtering boards to reduce hash/trash from SMPS filter by RThatcher on diyaudio (cleaner signal, better imaging)
Power Output
- Single amp is 8 watts per channel in 8 ohm and 5 watts in 4 ohm
- Monoblock XLR - 16 watts per channel
- Monoblock Bridged - 16 watts per channel into 8 ohm
- Monoblock Parallel - 16 watts per channel into 4 ohm
I have built at least 25 of these amps ranging from the basic 1.1a boards all the way up to torroidal amps with highly upgraded boards. These were used by my brother until he asked me to build him some torroidal ones for his Klipsch Chorus II's. I have turned a lot of people away from tubes with these amplifiers.
Asking $700 and I will cover shipping for free...
Shipping from Houston, Texas to anywhere in the CONUS.

The two silver amp camps have been completed along with the Power Supply!
these amps are now wired dual mono and each amp board has its own PSU board and transformer secondary. The front switches for the amps are not hooked up as switching on the PSU turns on both amps. This was done to keep the two power supplies separated.
Modifications and upgrades made to the amps as well from DiyAudio.
Umbilical cords are about 2.5 feet long.
