Unless you've owned this amp yourself, I'm afraid that you have absolutely no idea what you are talking about!
This amp is a first-rate piece of junk, badly engineered with the most miserable passive parts this side of a Griefkit (or more appropriately, a Monarch or Trio or Sansui of similar vintage!).
The original Hunt's capacitors are so awful that they are best replaced with 1 Megohm resistors, which actually would probably pass less DC across them than the original caps ever did.
As for the resistors, Allen-Bradley carbon composition types would be a very distinct improvement. The power resistors disintegrate, and all the electrolytics are utter & total crap.
The phase inverter doesn't even work properly, the self-balancing configuration guaranteeing that the inverter will always be hunting for some semblance of balance, and not find it...Disconnecting the feedback loop may even be an improvement, since in order for it to work, the distortion mechanisms being corrected must be repeatable & cyclical, which in the Stereo 20 they are not!
Leak did make some decent enough amps. Unfortunately, this ain't one of them!
An example of a good 'un is the original TL12 with triode-connected KT-66's. Shame about the crap power supply in that one and every other Leak (and QUAD), but such is the brand and is typical of the junk the British used to make. As opposed to the junk they made later & still make, which thankfully is easier to ignore than ever (Beard, Papworth, Michaelson & Austin, Grant, Lumley, Croft, De Paravicini, etc.).
