Beautiful Keenan! Inside and out
Hey - what are the PCBs connected to the rear panel heatsinks?

Okay the 45 parafeed rebuild is done, finally. Always takes longer than I think it will.
Here is the circuit first, there is a lot crammed inside.
Top.
Rear panel. Speaker binding posts sit behind the output transformers. Rear switch is for the headphone output.
Here it is with some tubes.
Bottom plate is perforated aluminum sheet for ventilation.
I like how compact this amp is, small footprint considering how much stuff is stuffed inside. It sounds great, spinning some vinyl.
Will have to go back in at some point to finely dial in the filament supply and I may better match the 45 CCS FETs, but overall it's done, I can mark it off the list! Will probably take some measurements later today.
841 amplifier is next...
Gorgeous! And you weren't kidding about thebighugemonstrous coupling caps. Is that 2 of them stacked together on each side? Sweet!!

Here is the 45 amp's final destination, back in the bedroom stereo with the Klipsch KG 1.
Just have a cheap Topping DAC and a Bluesound streamer right now, might upgrade the DAC to something fancy at some point. Sounds great though, very happy with the result.
Some of those old Klipsch speakers look like potential sleepers, underappreciated as they are not part of the “Heritage Series”, but sharing many of their characteristics: high sensitivity, flat 8 Ohm impedance, real wood veneer, mid-century style.
The KG series is highly regarded by many! Although many of the earlier models have a 4ohm impedance. The KG4 is a popular vintage model, 6ohms nominal, 94dB/W.
Sort of my 10 year hifi plan is to get a pair of full-sized horns, when I move into a larger home that can take them whether than will be something like the Klipsch La Scala, some vintage Altecs, or perhaps a DIY build using Great Plains Audio's new production 604 driver, not sure yet, just dreaming of giant speakers.
What the heck is going on when there are 80+ guests viewing this thread? Are you people or robots?! It's a little disconcerting, in either case.
Wasn't me I was working hard. If I had been looking in that would count as 50 - just ask @bcowen .
