point-to-point, hand-wired tube amps
who are your favorite manufacturers of point-to-point, hand-wired tube amps?
these hand-built amps that do not use PCBs (printed circuit boards) are getting rarer than unicorns, so i though i would poll the community here to see if there were any makers that i have overlooked.
a few extant brands that i have followed over the years are:
yamamoto soundcraft
kondo - AN japan
air tight
audio tekne
thoress
thomas mayer

Re: point-to-point, hand-wired tube amps
Ahem... PrimaLuna. Kicks the sonic butt for the price. Seriously. My Dialogue Premium HP EL34 integrated brings me more listening joy than ARC REF250SE monos with the 40th anni REF preamp did back in the day. Imagine that.

Sorry, I forgot that on this forum, if it doesn't cost as much as a luxury automobile, it isn't relevant...

I like my Yamamoto. That being said, it isn’t as quiet as I would like.

Re: point-to-point, hand-wired tube amps
It is minimal. For things like let's not make the user learn how to use a Fluke multimeter and stick screwdrivers into pots for biasing of tubes... Or when a tube goes bad, it will light up an LED saying I am busted... Instead of taking out half the amp circuitry with a spark show like can happen with others?
By the way, I have also enjoyed Shindo. A Cortese SET F2a and Monbrison combo with Tannoy Canterbury SE's. As much as I liked Shindo, the PrimaLuna is less limiting and sounds awfully close to all that Shindo magic. With the PrimaLuna one can use anything from EL34 to KT150 with a flick of a switch, so it is truly a swiss army knife of an amp. 30w of SET to over 100w of tube power.
Do AudioNote/Kondo amps sound significantly better over a PrimaLuna? I sure hope they do but I really don't care LOL... and I doubt a blind listening test would reveal anything even remotely resembling over $100k worth of a difference. But we all know that.

Re: point-to-point, hand-wired tube amps
somewhat goes with the territory i suppose -- certainly, higher levels of measured noise than with similar quality SS amplification. question is whether or not it is audible? perhaps more so with ultra sensitive speakers, 105+ dB sensitivity?
also, i have heard you mention the same with respect to air tight -- although others have reported them being dead quiet ...so, maybe its a system thing?viking acoustics berlin r mk2 | almarro a318b + air tight atc-5 (phono) | clearaudio concept + virtuoso v2 MM | t+a dac8 dsd + diy transport + roon rock

Jadis is good stuff but comes at a price.
Conrad Johnson, as far as I can remember had an interesting approach of using as big of a PCB as possible for all the parts layout.

Re: point-to-point, hand-wired tube amps
With current tech I really don't see an issue with PCB's being used. They perform the same functions as hand running wires, but there is a case to be made that these in many ways can be more reliable. Less chances of a cold solder (I have seen the part pucker machines in action). I do not think there is a man or woman alive who are as accurate, precise and can make a more solid connection. Even the software used in designing and feeding the part pickers are more accurate.
This is one area where I do believe that an argument can be made that the new technologies and methods might actually be better.McIntosh C49, MC152, MR85, R778 | T+A DAC 8 DSD | KEF LS50 Meta w/S2, KC62 (x2) | Rega RP8, Ania Pro, NEO PSU | Technics SL-1500C | Audio Technica VM750ML | Hexmat Eclipse, Yellow Bird, Molekula, Molekula Mini | Pro-Ject VC-E | Falcon NW PC Server (Roon Core & HQPlayer) | Microsoft Surface Pro 6 (Roon Controller) | Wyred 4 Sound ISO Recovery, DC Recovery | Abyss Diana Phi | Schiit Jotunheim 2 | Astell&Kern SE200 | Oppo BDP105

Re: point-to-point, hand-wired tube amps
certainly a 100% valid point -- and i don't see an issue either.
however, the counter argument that has been made is that P2P amps can be maintained / repaired as for long as there are qualified technicians on the planet ...and individual component parts such as caps, resistors, etc. are readily available. on the other hand, try getting anyone to repair a PCB anything without replacing a complete board whose future availability from the original manufacturer is questionable at best -- which at some future point leaves dumpster diving as the only viable source of replacement boards.
that being said, my purpose here is to simply compile a list of P2P amp manufacturers for anyone interested in this artisanal niche of the market.

Re: point-to-point, hand-wired tube amps
The trace conductors, if they go bad, can be fixed. I used to do just that back in my electronic tech days. Solder a jumper after scraping the trace. Other components are obviously removable from the PCB. Now, some of SMT (surface mount technology) chips, resistors, etc can be a real pain and so the whole board may need swapping out. In any case, obviously the old school, P2P wiring is simpler to repair but there is a limit to what can be achieved in terms of features and functions with such. Tube sockets should never reside on the PCB but some manufacturers do exactly that.... heat is not kind on that scheme over time.

Re: point-to-point, hand-wired tube amps
Some valid comments here--I bet I'm not the only one posting who has not run into situations as mentioned --
Potted line and phono stages/Potted Power supply filter blocks--Mfg no longer in business and no way of replacing nor gaining access to the components.
Take look inside any early Levinson PreAmps and see the butchers jobs some cowboys have resorted to get the things going after the Modules failed.
Wilson Xovers are/were potted but not such a priority.
Case in point I bought an Infinity DSP Amp from Arnie Nudell when they first came out--12 months later it died --or rather big Black potted box inside did and they no longer had any nor made anymore.
I contributed to Landfill.

Re: point-to-point, hand-wired tube amps
Another argument is that P2P is more susceptible to wiring issues. Far more chance of a bad solder, wire crossing, etc., etc. With few exceptions the chances of a PCB going bad is far less liking than something that was hand wired. Please do not think that I am against P2P, I am just pointing out the other side of the issue. I think both sides have valid points but reliability definitely falls on the PCB side.

Re: point-to-point, hand-wired tube amps
I have owned Croft Acoustics integrated/amp/preamps before they got popular with the Stereophile crowd. I find them to be very good, certainly very spartan, and won’t appeal to many. And measurements be damned, I love them. Even paying a bit of extra for imported goods, they just sound right to me. And of course, not chock full of any “audiophile approved” parts, and point to point wiring, only circuit board is for the timer circuit. Good enough for me.

Re: point-to-point, hand-wired tube amps
It is all personal preference, system synergy and even how we hear. I guess my inner music lover preferred the EL34 tubes and the PrimaLuna design more. Price wise, there is a significant difference but the inner music lover is blind to shiny boxes and cares not what the price tag is... (but that can go either way... )

I have known Mike Sanders (Quicksilver Audio) since I replaced him as National Sales Manager at Magnepan.
He wanted to start up his company way back then, and he did.
I have two pairs of his monoblock amps.
Are they the best tube amps that I have heard?
No, but from a musical involvement standpoint, they are extraordinary values when compared to amps that cost more than 10 times as much...

Tube sockets should never reside on the PCB but some manufacturers do exactly that.... heat is not kind on that scheme over time.
But on the flip side, if a PCB takes any significant damage, the repair can be a more costly and difficult - and that PCB may not be available anymore at some point.

Re: point-to-point, hand-wired tube amps
I’m a fan of P2P designs. My Quicksilver Mid Monos are super reliable. I’ve had them since 15, bought them used at about a year and a half old. I love them. They will soon be replaced by a Toolshed Amps 300b amp which is also P2P and I expect it to also be reliable.

Add Toolshed Amps to the list. I have had their 300b amp for a few weeks and it is awesome. So good in fact I am having Matt of Toolshed build me a preamp based on the 101d tube .

Ampsandsound use P2P for their loudspeaker amp line. Not sure about all of their headphone amps. Some are, some aren’t.
