Your Sony STR I belive had in input sensitivity of less than 200mV, which was pretty common for that time.
When CD's came out the defacto redbook standard became 2V-rms.
Your distortion problem could be as simple as the audioengine supplying enough signal to overload the front end of the...

A semi epiptic spring and suspensory pendilum. No "elastomeric" damping; but none the less pretty lossy. They settle out quickly in the verticle plaine.

The Wellfloats were gifted by one of the staff at Electori and Company in Tokyo after I had exressed interest in at CES some years ago. My contact at Electori has retired.
Electori did not as far as I know have any dealings with the Wellfloat company, this was simply a private...
Yes I have several sets. I've done demo's with a high mass plinth fit with an SP-10 MK II and various arms and hte whoe affiar on Wel-Floats. No one has ever been brave enough to smack the top of the plinth with enough force to get the stylus to skip. A small lateral nudge however is pretty...
Hi Kingrex
Yes quite familiar with potential ground loops, proximity of driven rods and ufers was rigidly spelled out by the DoE protocols and that I can test rather easily; but you bring up a very valid point, especially when water pipes are involved. Ground loop currents have the nasty...
Hi Ron
Chemical grounds are very effective if you can penetrate the earth and if you can keep the moisture content high enough to keep the electrolyte saturated; I would have a difficult time achieving either conditional. Water mains and branch feeders are plastic, so the days of grounding to...
I know old thread. NO not doing that, nor would I.
But living in an arid climate with a structure on a rocky hill has it's challenges. The first being that you're not going to drive a ground rod. Code allows for a UFER mat; 20 feet of 1/2" rebar in the foundation pour. In wet weather it...
I own most of those (as do most of us) and about the only time they get played is when someone from the local "audio group" comes over..... otherwise..... not so much. I tell the guys to go to the local music emporium.... be that a "music store" or a "Musical Instrument" store and find the...
As we look all the way back to the very first Pass Labs / Aleph-amps of early '91 we don't see any particular difference in reliability or mortality between those that have been in industrial service running 24/7 and those at home that are turned on and off on a regular basis.

No surprise there.
When I first started putting VFD's on motor drives (back in the "dark-ages").... the industry had a sudden spate of ball bearings dying prematurely.
Turns out there was induced circulating currents in the bearings from the switchmode power supplies. Before the bearing...
The Pass Labs D1 was difficult to build as a result of ever changing parts availability; and it went against one of Nelson's basic tenants that the factory would have no un-supported orphan product for the foreseeable future.

I've had KAB Acoustics rewire the arm on an SL-1200, with their best wire...... I presume it is better.
Having said that the arm rewire came along with their outboard PS and strobe disable function, and their bedding tweak for the bearing This does make for a better package, but...
Try "Service@passlabs.com"
I'm sure the factory will try and address any questions you may have. They can get very specific if you happen to have the serial numbers of the amps
Honestly I'd start with some contact cleaner like Caig and call the lads at KAB Electro-Acoustics for some factory oil for your SL-1200's platter bearing and go from there. Kevin has a long history of worthwhile upgrades on the SL-1200, and seeing as yours is already paid for, a few tweaks to...

The hardware is bigger than the operator and fully capable of retaliation.... no whacking.
Case in point... the navy lads built us a nice resonator tank... the designer apparently knew how to build submarines. So we get this cylindrical pressure vessel thing 20 feet long, 8 feet in...
Naw, just like being an audiophile.
RULE OF THE FIRST Keep "off' button in reach and one eye on the meter.
And from there: Push buttons, turn dials till you get what you want.
Stock pile lots of wire and solder and sometimes put your faith in things nobody understands.

I can only speak to the Pass Labs XVR-1 product. Generally the Pass Labs factory spends time with the end-user and tries to send the unit out of the factory with the "best-guess" starting point documented and established. For units that are out in the field, the same sort of process. However...
I concur. back in the day it was routine, edge cards came out, went in the dishwasher on DI and filtered water with Alconex. Dried in partial vacuum, then re-greased. Space qualified hardware.

Does this count as collecting? I have a box full of un-used airline "baggage stamps", going back to the Wright Bros Mail Service and ending with the "Connie". I give it a good looking over, once every 20 years or so.

If tools and tooling count, then I may have issues
It's amazing what a walk through the McMaster Carr on-line catalog will turn up. Spiral wrap, raceway, slotted wire duct with PSA backing. Too much stuff that you need and never knew you needed. Easily, many nights of interactive mischeif.

Maybe a little hard to get a visual on. My equipment is mostly spread out left to right. There is a HD steel chassis power strip (ie raceway) running behind the rack on the floor and right against the wall, hardwired into the mains.
Power cords go straight back for about 6" (300mm) and...
