My sympathies - same over here. In my head, I have unfunded projects for years to come ...
.....and add rafinement, subtle sound colour shading, precision in soundstage width, dept AND height ... - it is at low level that it will improve the most. - so, order the parts needed - what are you waitng for !!??
It will not reveal its true nature after the last board is done and the whole does not work for continuous operation of about three months ( just play FM radio trough some cans in a drawer when you want silence otherwise ). You should see the innards of my CD-R recorder - THAT is crowded. Off limits for photos - beleve it or not, I had to trim the screws that hold the box panels together to just the lenght required to hold them in place - NO space for additional 2 mm or so...
THE way to go ! Specially about those ghastly sounding and unreliable tantalum caps - THE FIRST thing to go chez moi are always tantalums ... If such/similar job is done thoroughly, the amp (receiver in this case) can be considered to go in one's heritage - film caps last more than a lifetime - and get better with age to boot !
True. Some of the better discrete tape quad recordings from the 70s or so found their way to multichannel SACD releases - which is the first time general public gets to hear quadro as intended. 
It is SIMPLE. I do change one thing at a time - not many. For example - only preamp in an otherwise same system gets replaced at one time. Or cartridge known to have different absolute polarity ( in lack of proper test record, run-out groove with the "click" each revolution will do just fine observed on a scope )  But I will try as many options as available. And see if there is any pattern to what can be heard. I have to do the normal work, like editing the recordings etc...
To be blunt how I found out absolute polarity is audible: 1. DC coupled high voltage electrostatic headphone amplifier with matching headphones2. AGI 511 preamp - although not DC, it is VERY near - to arround 0.01 ( one hunreth of a Hertz ) - 3 dB3. Various phono cartridges ( for one reason or another, it is possible to get 50/50 cartridges either in correct polarity or inversed polarity in the same batch - and they do sound different when obeying their colour code; if...
THIS belongs to analog porn thread... - the light in appropriate colour is already in place ... Congrats , how does it sound ?
My only true experience with quad is from early/mid 70s, when I was still in elementary school. Akai representative held a demo in an acoustically totally unfit place ( the whole "wall" was actually giant glass plate, a window on the street ...) - and they played TOTL Akai gear. I had a poor cousin to the   at the time - and STILL did not find the quad, as demoed, nothing to write home about, let alone worth the difference in cost that was beyond my comprehension at the...
It would, of course. Problem are records ... - and SIGNAL TO NOISE RATIO - it was the whole of 35 or so dB in quad... It is much like buying Elcasette tape machine today - where on earth you will get the Elcassette tapes ? Same with WELL PRESERVED quad records today ... - if it has HF carrier (30 kHz +, depending on system ) worn away/damaged, it is no longer a quad record, but merely stereo one ; no decoder can help in such a case. ( said a guy who will, against all odds,...
