Joseph Tang to lars.tomasson


I am looking for the schematics for my 20 some years old Superphon Revelation Basic Pre-amp.
This amp is definitly better sounding than my ARC SP-7 Modified. However, when I had the internal wiring
changed to CADAS . I reversed the +/- Power and burned one channel of the Phone Section's transistors
(blew 3-4 transistors). Any idea to look for the Phone Section Schematic, I have the Line Section Schmatic.
Plaese email me joseph.k.tang@gmail.com if this can help.

Summary:
Tried this for kicks. Good performer(given the price and diminuitive looks) One of the better SS Preamps I've tried. Sounds like a hi-end preamp. I do agree with one of the reviews "lean bass" I was hoping to get some feedback on how much I should buy this for.

Strengths:
Open sound stage, transparency and immediacy.

Weaknesses:
Looks and perhaps age

Solid State: Metaxas Marquis, NAD3020B. I do have Tube gear as well which should not be compared against.

Price Paid:  $500.00

Summary:
Bought this new back about 1993. I have a Revelation II with a single volume control. I listened to many preamps when I purchased it including Cary, B&K pro, Adcom and some others. I found the phono stage superior to anything I heard. Its still works like the day I bought it. Very clean and natural. Only problem for me is that there are not enough step levels in the volume control at low levels. Thinking about buying a new preamp but may continue to use this as a phono preamp.

Strengths:
Quiet, nice switching and handling of tape recorders

Weaknesses:
volume control range - but no noise after all these years

Similar Products Used:
These date me - GAS Thaedra, and Crown IC-150(how did this ever become a classic???)

Price Paid:  $150.00 from second hand

Summary:
This is for the Superphon Revalation II. Good sounding pre-amp with phono stage. For the price it can''t be beat. If anyone has schematics, or knows the pot adjustment procedure for let me know at lars.tomasson@att.net

Strengths:
Great Sound quality, Has a phono section, enough switching capability for most people, doesn''t do anything wrong. Still works great after 12+ years.

Weaknesses:
Not much to look at, Dual volume controls are a little inconvienient, Company no longer in business, little consumer following.

Similar Products Used:
Conrad Johnson (a little better), Audible Illusions Modulus (as good but a pain in the but because of the tubes and high DC offset on outputs if power is momentarily lost)

Price Paid:  $250.00 from Jeff's Sound Values

Summary:
I used to own a Superphon Basic preamp. (the one with two volume knobs) It actually sounded quite good but a little lean on low end and somewhat hard to control channel balance. I recently purchased a Superphon Revelation 2 (one volume for both channels) It sounded fair but had lean low end and a shrill high end and midrange. Not something to live with as it was. I read on this site someone recommended changing the caps to Blackgate for good results. I spoke to the designer and former owner of Superphon about possible mods. He was very gracious and suggested the Blackgate substitution. Well, I just installed them today and........WOW!!!! Are you kidding me??? I couldn't believe my ears. This was a totally different preamp. The transformation is ridiculous. The sound is crystal clear. The bass is all there and treble is beautiful. I would have never thought changing two capacitors could make this difference. If anyone has one of these, order the capacitors from Michael Percy and be prepared to be astounded!

Strengths:
Inexpensive, neutral, clear,natural.

Weaknesses:
A little dated styling. Perhaps slightly deficient on low bass??
