So here’s the upgraded set up from top to bottom:

Linn LP12 with Ittok LVII tonearm and Dynavector DV 10X5 cartridge

Metrum Acoustics power supply and DAC

Audiolab 6000 CD Transport

Croft Vitale pre amp (the only component apart from the speakers that survived the upgrade)

Trio L-O5M monoblocks

and out of the picture, a pair of B&Ws on the wall.
I had the 10x20 for many years on my VPI, was a great cartridge. The Benz Micro Wood finally dethroned it.

Nice but are you not concerned about heat? Mono blocks don’t look like they can vent heat very well down there.

It’s the angle of the photo I think. I had a guy here to set up the new arm and cartridge and asked him if he thought the monoblocks were positioned ok and he thought they were fine.

As long as you have enough air around them you should be fine. If you find them getting too warm, buy a micro whisper fan like the kind they use in computers and put it at the back of the rack to draw air away. I did this with my Audio Research D51 which had a horrible design for heat (literally trapped it) so I just wired up a pair of whisper fans ( from an old computer tower spliced into wall warts of the correct voltage) and they are wired into switched outlets on the power conditioner. Can barely hear them and the top of the cage doesn’t get warmer than slightly above room temp.

Welcome! I own/have owned all of the above except the Canary, and you have some true classics. I had a pair of those Kef’s once (my boss has them now in his family room) and they have amazing imaging- like shocking 10 feet behind the speakers imaging.

The 104ab's are true classics. But what happened to the Dynaco cover? 😎

They're great speakers for sure, especially for the money. A few years back I found a pair of 104s (non ab version) for $200 on local classifieds and bought them for my dad. Then I found a pair of 104ab crossovers for $150 and "converted" the 104s to 104ab's. For $350 all-in they replaced his Harbeth P3ESR's (costing many times more) as his "main" speakers.

I bought the Dynaco without the cover, unfortunately 🙁

Thanks! Maybe this will be my Christmas present to myself 😁
Just stay away from the mod kits. I have a PAS3 that was perfectly fine but is now in pieces becuase I got a wild hair and lost interest half way through. 🙄 Maybe I’ll get back to it when I retire in 20 years.

Oh yes, I know this all too well. It can be quite the rabbit hole. I've made a rule of only buying fully serviced/recapped vintage tube amps.

That being said it's definitely on my bucket list to take a dumpster-destined vintage tube amp and fully recap/restore it on my own. I've dabbled with replacing the odd blown resistor here and there, but fully rebuilding an amp is not for the faint of heart!

Agreed-and have no affiliation with Dynakit
Parts, but it would be fun to build one from the kit. I have rebuilt many amps/pre’s and there is great satisfaction from repair- but I’ve never built one from chassis up.

Harmon-Kardon Citation II. I have rebuild plenty of Dynaco in my day. The HK is a better amp.

The citation tube stuff is pretty wonderful. Bogen actually ripped off their design for their domestic line (as opposed to commercial) in the early 60’s- I believe there was litigation. I had the Bogen RP60 (the Golden Bogen) and it was a sensational receiver.

Back in the day we would second-guess the designer, especially the Dynaco. Mind you, the paraphase inverter worked mostly fine, and that's what feedback is for.

But using a differential amplifier as a phase splitter was much more better. I regret that I never had a chance to desigin and build one. Maybe some day.

The problem with Dynaco equipment wasn’t so much the design, but the parts and design had to allow for a specific price point. I have an ST70 that was rebuilt with no compromises and it a very nice amp. David Hafler really has some excellent amps during his career.

A friend of mine who did repairs for decades finally designed and built his own amp based around 4 KT88’s, 2 tube rectifiers and 6SN7’s for input (his favorite tube). He sent his final design to Bob Carver who gave him feedback on how to improve the design- apparently Bob is very approachable.
I look forward to the demo of your amp, Tom.

I used an ST-70 for over 10 years before I got my Canary Audio CA706. Great amp, I miss it.

If you ever encounter a Stereo 70 rewired with silver-plated wiring with white Teflon jacket, regulated filament supply... that was mine. 😀

Most of the circuits are pretty simple. The output transforner is what matters. The last set of Dynaco I rebuilt, I did the Audio Reseach trick, and used the outut transformer secondary between cathode and ground in the output stage. 8417 output tubes, taped off the usual plate tap and used the screen tap. To derive the screen, used a transistor with a Zener diode on the base to fix the voltage.

I often wonder where those amps ended up. 😀

There is a collector of ADC B100 preamps... he has my former preamp. It was amusing to identify it to him!

That sounds interesting, I'll have to look into the PS upgrade. Mine has the tonearm rewired with an analog/ground outputs done by KAB. Also put a higher mass headshell with a HOMC Denon DL160. It did improve things and it fits my system in terms of being non-fussy and fun, if not a little sterile. Toyed with the idea of putting a SME 3009 on there but decided to stick with the Technics arm and make light mods (maybe a fluid damper later on). I'm guessing isolation or decoupling the deck will probably help too.
I have the isonoe footers on my 1200 with the precision sound PS, also a funk firm platter mat. Funk also makes some feet for 1200s.
