Cello Palette w/ Capacitors

Use the preamp! They were made to very high standards. If you do have a tech go through it, tell them NOT to do any work other than cleaning without your explicit permission.

I owned a Cello Palette Preamp for over 10 years. I sold it for more than I paid for it.

Very fine equipment, and as @tonykay said, always in demand.

You might want to check whether you have the Cello Palette Preamp or the original Cello Palette. The former had MSRP of $8,500 when discontinued; the latter, far more. And that was at least two decades ago.

It is the original, with the larger knobs. The prices seem to vary wildly! I have the preamp, power supply, and "cello strings" . I'd use it, but its not really my lifestyle right now. I am thinking about posting it on Audiogon or selling to a broker. 

I have a set of caps for it as well--I am not sure if they are the new or old caps nor why my dad was replacing them (upgrade or needed repair)

You have a very, very fine piece there. Why not keep it and use it to bring music into your home and life? Assuming it's in good operating order, it could bring years and years of pleasure.

My feeling those capacitors are back up parts, Mark Levinson said cello parts are costum made and they are are to find.

I hear you on the "keep it" front. it certainly seems like a great option if I can--the resale of these things seems very complicated. The problem is that this is just one piece of a huge collection of stuff, some of which is in working order probably, but its filling up my mom's house, she has hearing loss and no use for it, and I am probably soon going into a graduate study program where i will need to be mobile and live like a pauper. I mean look at this list--and this is just the "audiophile" stuff excluding some big speakers, horns, subwoofers, ...

McIntosh MX135, Lexicon NT 512, Luxman M-O2, Magnum Dynalab ft101, VPI hw-16.5, Theta ds pro V, Oracle Delphi mkIV, Advent model 300, Proton AA-1150, Dahlquist DQ 10, Mark Levinson no. 23.5, Alpha design lab gt40, Audio Research CD2, RGPC 400 mark II, McCormack micro phono drive MPD 540, Mcintosh MR78, Cello Audio Palette, Revox A77, and Magnepan MG III-A.

Not to mention a metric ton of specialized cables. It is just not in the cards for my lifestyle at the moment.
