Heard them at Joes. Sounded VG with His Horning speakers.

The Aric looks very interesting thanks. Considering Border Patrol, Audio Note and Coincident so far.

Still looking.

Beautiful amps...and his dac has a good reputation

I was using the Lamm ML-2 however sold. Audio Mirror makes a good amp. All I need is 1.5W to drive the 102db Rethms. Was using Amps I sell. I do not sell a 45,300b, etc Amp. Was thinking Shindo, Audio Note, Airtight, etc.

Take a look at the amps from Triode Lab and their sister company, Finale Audio built just across the border in Toronto. This pair is $5500 CAD so about $4300 US.

Thanks Jack.

Hey Charles. Sorry if I missed it but are you looking for a product to carry or just something to be best able to showcase the speakers.
I would look into 2A3 or 45 power. When I had the Usher D2 speakers (98dB with TAD horn), anything from 1.5 warts provided a great presentation. I loved the 45 amps I had with them.

Personal use. Thanks.

Hi Charles, while it's no longer available, it was the Welborne Labs 45 mono blocs. If your only looming for something for personal use, maybe have someone custom build the perfect amp for your needs and preferences.
-
Radu Tarta at Simple Pleasures will custom build any amp you want. Would love to own his turbo 45 based on the 45b tube from EML. He’s a great guy and has done some work for me on my preamp.

this looks like it might be another contender:

I’ve always wanted to listen to one of these in my system. But sadly, I can’t ever recall having had a speaker efficient enough to be driven by something like a Yamamoto.
-
Thanks Guys. Lots to choose from. Leaning towards a 300B or 45. Tektron has cauht my attention. Roger and Doug really appreciate your suggestions.

Other than Border Patrol and Audio Note any suggestions for Rethm Saadhana speakers at 100db ?
charles
Charles, have you considered Pro Musica's 3rd generation upgrade to the Stereo ST-70? After you audition
one of those amps, you won't want a dht amplifier, and I have audition both 2nd, 3rd generation
and dht amps for some 20 years. Pro Musica blows them away in every catagory including "in touch with the music". Dan has both 2nd and 3rd generation amplifier with his LS3/5As, Harbeths etc and virtually nothing touches them.
Just something to check out, if you can find one, if you get a chance.

Did a search and couldn’t find anything on a Pro Musica ST 70 mod. Can you provide a link?

Pro Musica retired, or the guys at least separated some years ago. Difficult to find an amp, Dan found one just a few months ago and immediately snapped it up. So it may be very difficult to find one since few sell theirs.
Don't mean to be a jerkish, just that if you find one, and it works, buy it. Even if a transformer is bad, you may be able to find a used tranny to repair it.
My amps were more accurate, but I never had a descent chassis that looked good and could reliably ship, nor nice looking trannies. That is why I mainly stuck to pre-amplifiers. UPS is nortorious for damaging products, FedEx seems a little better.
DHL was by far the best when they were around.
cheers

Steve,
Did another search and found this. Can’t say I’ve ever seen an ST 70 look this good. The only time I’ve really suffered severe damage from shipping was with Fed Ex. Beautiful speakers I returned to manufacturer were pretty trashed. Had them insured and Fed Ex paid claim promptly.

Unfortunately, Pro Musica, Champaign Illinois, is out of business. Yes, this amp looks nice indeed.
When I started in business, UPS damaged just about every professionally double boxed preamplifier. Found out that in
Chitown, a box can literally fall 50 feet. Very early on, tried FedEx and was better, although still some damaged packages. Switched to DHL had no damages at all, not one. Shame about DHL basically closing out USA.
As I recommend, if you find a Promusica Upgraded ST-70, esp 3rd revision, get it.
cheers

Looking at Tektron. Can use a 2A3, 45 or 300B..
charles

I recently finished the design for my personal amp. I have to have different amps for testing other products. I am going with a traditional topology using the 300B for about 8 watts. Will be using upper end components but not overboard. Do have a few "tricks of the trade" that will be utilized that I have come up with over the years. Hope to get some time to start the build over the next few weeks.
This will not be a production product. Strictly for personal and testing purposes. I simply love the 300B sound.
I am [considering] an 845 build down the road.
Any decisions yet Charles on your amp?
-
No not yet. Not in a hurry a whim thing. Using 211s now. Also have an Audio Hungary pair of mono blocks using 6C33CI. A pair of Audio Note Legend that needs repair as is was damaged in shipping.
charles
-
Very nice. 211s are power houses. Really like the 6C33 as well. Had a few amps in the past that used these tubes. Forgot about the 6C33. May have to put that back on my list.
Right now working on the purity Master Reference preamp. Been working on this design for the past several years. Prototype auditioning has received great feedback Finally ready to start the chassis design. Can wait to pair it up with the 300B amp. Now I just need a few more hours in the day. :duh
-
i saw these; look pretty interesting. i know manley makes nice amps; i had a pair of mahi mahi's; i should have held on to them longer - shortly after i sold them, manley more than doubled the retail prices. even then, they were worth it, imo. but an absolute steal, prior...

Fairly local too, which is nice.

Thanks for heads up. I would have to hear before a purchase.

Well, they are in NJ, so not too far if they were something you were interested in...

Again thank you Dougster.

Picked up an Alan Eaton 45 amp. GE 45s and Sylvania 45s. uses 6SN7 as well. Point to point. Now 45 tubes are next. Emission Labs ?? The 6SN7 are Russian. Tungsol coming from Vintage Tube service.
charles

I'm guessing this one?

That is the one. A start.
charles

Doug the Speakers are 102db. Will listen to the 45 supplied Sylvania and GE. Then will play around. with 6SN7 or Emission Labs 45 and Hitachi 6SN7.
charles
-
Thanks, me as well. Eaton gave me a price of 3K for His 300B Mono Blocks if the 45 does not work out.
charles
-
if you buy direct from eaton, you may want to consider his 45 or 2a3 monoblocks.

Thanks bought 45 amp. Want to compare to a Tektron now. Which can use 45, 2A3 and 300B with flipping a switch. However this over achieving Eaton 45 design is so F'n good it just may be tube types now.
charles
-
i know, charlie; i was just suggesting 45 or 2a3 mono blocks from eaton instead of 300b's, if you decide on checking something else out. iirc, i suggested the eaton amps to you... ;)
glad it's working out! :thumb:

Thank you Sir. Now looking for RCAs Ballon 45s. Found a pair at $600 NOS. With that price maybe EML 45

if you have to have the globes, you could try these:
https://www.ebay.com/itm/114408339185 (https://www.ebay.com/itm/114408339185)
these may sell for a bit under $600; hard to say...
https://www.ebay.com/itm/164384287695 (https://www.ebay.com/itm/164384287695)
also, in looking at these, i checked out the eml's. many folks prefer them over the vintage rca's. and there's some difference between mesh plate and solid plate. but, based on one reviewer's comments, (srajan ebaen), since you're using the 45 amp w/ a speaker that has powered subs, you might prefer the mesh plates? even tho srajan said he liked the solid plates better.
