Noise cancelling...
now... I know this sounds crazy... but all that noise that gets cancelled... I think it pops up someplace else in space-time. THAT would be a bad time and place to be when it happens!

Re: Post a picture.....any picture...part deux...
Ed the SRT King and I met in PA to visit Carl. I came home with some projects....
An Eico 667 from Carl in pretty nice condition for its age. The Sony TC-440 R2R was out of a console. Ed found a wood cabinet for it.
The exterior could use a paint job. Or leave it as is...
The Sony TC-440 is a four track two channel stereo deck with three speeds, 1&7/8, 3.75 and 7.5ips. It sports a Roto Bi-Lateral Head system which physically rotates the head stack to allow true bi-directional (auto-reverse) recording and playback using one record and one playback head. Typical bi-directional record/playback decks have six heads, two erase, two record and two playback. This one has two fixed erase heads and they rotate the one record/one playback heads for reverse.
Carl had some extra knobs from a Sony.

I can guarantee you all that I am pointless.
That said, and speaking of old(er) things...

Nifty solution
I've had a heck of a time swapping certain discrete opamps in the Keces HA-171. The desktop chassis and smaller pcb makes space limited. I really don't like the sound of LME49710 opamps at all. They are popular because they have high gain and make music "pop". But to my ears they are shouty, shrill, edgy and in every case I get listening fatigue pretty quickly.
The final output stage of the Keces uses one. The Dexa Ultimate II discrete op-amps are modeled after 2A3 tube sound. They are very smooth, engaging, throw a huge sound stage and detailed and fast but the opposite of edgy, shrill and shouty.
The way they are packaged made it impossible to use without one of the caps (brown Elna) getting in the way. Originally I used a 35mm 8dip socket extension that raised it up over the cap, but they the lid didn't fit. It's too far away and it starts oscillating and becoming noisy, etc.
DC at the output was close to 90mV (not good). But there were other things that caused the DC issue, but having it raised 35mm above the pcb didn't help.
I was using AI to come up with a solution and I found these from a company called Electronic Surplus. Before consulting AI I tried to Google Right angle dip 8 socket and nothing came up.

Worked PERFECTLY for what I needed.
Thought I'd post for anyone who this solution might work for. Didn't know these existed.
