Thoughts on Audio Research D70


I recently saw a very well priced D70. If I remember back in 80's these were highly thought of. Having no chance to hear, what do they compare with today or do they?

I have a batch of 0.1, 0.22, and 0.47 FT3s laying around.
Cant use them anywhere other than my point to point wired projects. Too big.
All my Vcaps are deployed in various pcs of existing gear.
Are yours branded ones or generic Russian? Definitely not the Psvane Audio Teflon leaded caps right?
Tried to send you a PM but cant get around this user interface merry go round (pun somewhat intended relative to the Moncrief merry go round :) )
Hifikeek1 and Johnsonwu, IF you had an unlimited budget for cap replacement, which caps would you use in the D70 or the D115? and why?
@HifiGeek1: Audio Research seems to source caps from The Reliable Cap company (Audio + Rel) and TRT (which some think is sourced from ASC). I will pass on big sized caps for now. Even the 0.47 I have I couldnt find anything to fit them in.

@DaveyF: For coupling caps I would say V-cap Teflon TFTF or Mundorf Silver Gold Oil. Tried/have them on many friends'gear as well as my own. Never tried the Duelunds, no I didnt win the megamillions lotto. Jensen ceramic caps, maybe, too expensive still.
@Hifigeek1: I was trying to do some final checks on the regulated voltages to the first stage B+ and regulated screen grids and I found an ultrasonic oscillation of about 20mV peak to peak. My mistake for not turning the horizontal dial of my scope all the way to look at ultrasonics. Thought the 20mV was just hash or the probe.

This was traced all the way back to the plate of the 12AT7, and then back to pin 6 of the TL071 (U1) which was sending 100mV of sawtooth.

I'm leaving this for another day now but am curious if you think I should replace the 3 0.22 caps surrounding the input pins of the TL071 opamp.

Much appreciate any guidance.
