I'm sure those Phase linear pieces will get some attention.
The 400-1 was bought by me from QC stereo in Bellingham, in the 70's. '77 I think. It suffered a failure in operation some years ago and seemed to go into a parasitic oscillation, that caused the VU meters to swing full on and pin to the high end (though I don't think it damaged them) I mothballed it at that time and haven't looked at it since. The original panel bolts have vanished.

Pioneer built some pretty nice stuff in the mid to late 70's. My Pioneer SX-1250 still is my sentimental favorite. In addition, I am bringing an inexpensive Pioneer Int. 40 watt per channel SA-6700 as part of my "Cheapskate Pabst Blue Ribbon" system to Carverfest. Never a problem, also made in mid to late 70's. Bought used from a neighbor about 25 years ago for $25 for a system I put together for Dad back then. Not the Spec 1 quality, but has held up very well over time.

No, there's a Pioneer CT-1250 though. It was Pioneers top of the line cassette player of the time, with all kinds of bells and whistles. Trouble was, at the same time as Pioneer went to the snappy looking blue light bar level meters on their cassette machines, they changed their transport design from the bulletproof and totally reliable one on the CT-750 which I had one of, to a new one that on inspection relied on a really oddly contrived belt slip setup for the reel tension device and the same belt with the motor running at the same speed for the forward and rewind functions! In practice, as soon as the belt developed even mild hardness, as they always do, the takeup tension would become so weak as fail to turn the tiny load of the cassette reels, causeing the machine to detect stopped reels and kick the transport off. That and/or the machine would be unable to fast forward or rewind the tape. The only way out was frequent relacement of the belts with a brand new ones.
For what was supposed to be a manufacturers flagship premium tape player/recorder, this was an incredibly huge design flaw.
I wondered if the engineer responsible for this travasty was made to sit cross legged and bow in shame, and cut out his steaming entrails with a sharp sword after composing his apologetic death poem.
The seller took no responsibility upon himself for the damage, and that was in earlier days of eBay when there was less onus on a seller to uphold his end, he had his money and it was hardly worth the effort to dispute. (I did carry a dispute to its end once over a poorly packed CD recorder/player and was repaid minus 'deductible'. The whole process took months involving dozens of emails and documentation)
If you want I'd be happy to send it to you for parts, for just the postage and a beer. I'll throw in the operators manual.
I think what you're looking at below it is an early 70's Pioneer SF-850 electronic crossover. It not only has steps for separating stereo RCA jack inputs into three ranges of two channels each but the cutoff slopes are adjustable by 6-12-or 18 DB/octave! It's a rare bird and I think I'll keep it for the retirement package.
