Sorry. Everyone. For some reason I’m not getting notification emails.
So far, the two M2x monoblocks, Small ACA monoblocks, and the ACP preamp have all sold!
-
During the last year, I have spent a lot of time building Custom Nelson Pass Class A Amplifiers, preamplifiers, and headphone amps and I need to start selling them. The amps I have been building are all from boards I get directly from diyAudio.com. I have listened to push-pull tube amps, SET tube amps, vintage amps, and even high powered class D amps on my Klipsch Cornwall III's, but always find myself enjoying the Nelson Pass amps the most.
Below is what I have available for sale:F6 Power Amplifier in Silver Steel Chassis

- Asking $1000 shipped.
- M2x monoblocks in high quality black chassis with 10mm faceplates - 25 watts per channel into 8 ohm and 50 watts into 4 ohm

I built a Nelson Pass m2x with parts from DIYAudio for a friend in a large modushop 5u chassis. Just last week he asked me to upgrade it to an F5 Turbo, so now I have ALL the parts to build an M2x except for the chassis, IEC, rca inputs, speaker posts, and screws/standoffs. I currently use a pair of M2x monoblocks on my Cornwalls, so I do not need to build another amp. I am asking $280 SHIPPED for all the parts.
To finish the amp, you really only need to spend another $300 for the chassis, and $50-$60 for everything else. That gives you a nice Class A amp for under $700. I have built an F4, F6, F5, F5 Turbo, and the Amp Camps and this amp has by far been my favorite performer from the pass line-up. It has great mid-range, solid bass, and has a more tube-like sound than the other Pass Amps.
What you get is:
- 2 Fully stuffed m2x boards with Tucson boards installed
- Antek AS-4218 with Transformer cover
- 2 35A Monolithic Diodes
- 4 Brand new Keratherm Pads
- Power Supply Board with 60,000uf per rail
- 2 new Cl-60 for the power
- 4 pairs of un-stuffed Daugther Boards
- Roll of mu metal to put over Edcors if you have hum

The Jolida Amplifier has SOLD.

The JOLIDA CD Player has SOLD. I am dropping the price of the JD-302B tube amp to $650+ Shipping.

Pics of the F4s below along with the BA3 FE. Both were built in the DiyAudio 4u deluxe chassis from DiyAudio (BA3 in the Pesante 2U) and have genuine Toshiba JFETs. I also included XLR inputs for both amps.
-
Sorry I forgot to mention. The BA3 Front End preamp I would do $400. It has a Kubota Power Supply, Clarity Caps, Toshiba JFETs, and a nice stepped Attenuator A3 from Glassware. The selector switch is also from glassware and it has 3 inputs and a Tape out I included for my headphone amp. Once I get home I’ll send more pics.
Right now it has perfect gain for my F6 or M2x but two resistors can be changed out to increase the gain.

I just wanted to chime in on what I settled on for Pass Amps. After listening to the m2x, F4, F5, F6, Upgraded Amp Camps, and Various Tubes amps (Bottlehead 300b/Bob Latino VTA-120) I settled on the F4. It is clean, crisp, fast, and VERY detailed. I built a BA3FE preamp as well as a Pearl 2 Phono from PassDiy and now my tube gear is all in the closet collecting dust.
Sure I liked the tube sound, but the F4 has a little bit of everything including some warmth and great punch in the bass. The m2x was the most tube-like, but it also had looser bass and not as much crispness on the highs. It kind of reminded me of the first time I rolled in Mullard CV4003 tubes. Great mids and bass but did not have that sparkle on the top.
If I had to rank the Pass amps in order of use on my Klipsch it would be:
- F4
- Amp Camp with Torroidals (Upgraded Capmx Power Supplies from Rudi_Rozek on DiyAudio and TungstenAudio's changes)
- M2x
- Nelson Pass' Amp Camp (Upgraded from TungstenAudio's changes on DiyAudio forum)
- F6
- F5
- Nelson Pass' Amp Camp (no upgrades or changes)
I currently have two matching F4's with XLR inputs and adapters to tie together the rcas and run the amps in parallel. I am going to try F4's as monos and see if I can hear a difference between just one even though the current does not increase into 8 ohms.

Thanks for the feedback. Should I just message bob for his input?

I have a friend that had some spare parts pulled from a single La Scala and I was wondering if I could build a Cornscala with it to use as a Center channel with my Cornwall III’s.
I have a KT77 Tweeter, A-55-G squawker, and a Dean Wescott La Scala crossover. I also have some spare Hawthorne Augie 15’s but not sure if I can incorporate them somehow in the build... Thanks.

I currently own a pair of Klipsch Cornwall III's and have been bouncing around with different amps to decide what I like the most. Right now, I am in between a Bob Latino VTA 120 I built and a Pass Clone M2x I also built. I love top end and detail I get from the VTA-120's KT88 tubes, but the bass from the M2x is so punchy and tight.
I have an SP-12 preamp from Tubes4hifi that has two outputs. Can I SAFELY biamp the Cornwall's but using the VTA-120 tube amp on the mid/high and Pass M2x on the lows? I see a lot of people saying it is perfectly fine, but others mention it is bad for your amplifiers. I do have a volume knob on the VTA-120 i can use to even out the output to match the M2x.
Any feedback is appreciated.

Just a quick update on what I decided to keep for my Cornwall IIIs. I ended up building an F4, F6, M2x, and about to build an F5. Upon listening to the first 3, I thought the m2x sounded the best with my tube preamp, especially in the mids. The F6 was very detailed but not as punchy as the M2x. The F4 was the most detailed of all, but I did not have a preamp to fully test it.
The Akido all in one has given my VTA SP-12 preamp a run for its money! A sleeper DIY tube preamp IMHO.
-
I'll ask my friend if he would like me to sell them. He may just have you call his store and he can ship.
-
Sorry, I do not know why this thread posted three times. Please remove.

After research on them, you can only find them on European websites. They equaled out to about $650 per mono block amp after conversion before shipping.

My friend that owns an audio shop hads a customer who sold off her deceased husbands stereo gear, and included in the mix were boxes and boxes of DIY Kits that had been purchased, but never put together. I had some experience building Bottlehead, Tubes4hifi, jdslabs, & Elekit units in the past, so he asked if I could take it all home and help get it all built for him and he would allow me to have a few of the items. After days of digging through all the boxes, I pieced together all the kits (some of them I have already built):
- 6 DiyAudio Amp Camp Kits (Finished 4 of 6)
- 2 Hypex NC400 mono blocks (Finished)
-Aikido All in One Preamp
- 2 Decware Zkit SE84's
- Elekit tu-8500 Preamp w/ Amtram upgrades (Finished)
-Elekit tu-8340 EL34/KT88 tube amp w/ Lundahl Transformers & Amtram resistor upgrades
- Bottlehead Eros, BeePree Special Edition, & Kaiju Special Edition (already built the Eros)
-2 DiyAudio Passlabs F-4 Amp Clones
-1 DiyAudio Passlabs F-6 Amp Clone
My main question is, which would be the best kit to keep for myself to experience with my Cornwall III's?
I currently have a Bob Latino VTA-120 and the SP-12 Preamp from Tubes4hifi that I built. I am leaning towards the Bottleheads (300b's would be fun), the Elekit tu-8340 & 8500, or one of each of the Nelson Pass clones.
Thanks.
