Blackgate mod for the Superphon Revelation Basic?

BE EXTREAMLY CAREFUL AND DISCHARGE all CAPS(>35V/>.22uF) BEFORE TOUCHING THEM!

use 10k/5W wire-wound resistors with isolated alligator clips connected to the capacitor electrodes

Renewing just 2 caps might not be worth the time invested v.s. the sound. E-mail Michael Percy(from www.percyaudio.com) that might advise you for the better upgrade path.

Why not contact Stan Warren and see what he says ? He built / designed the unit and would know better than anyone if it was worthwhile to do. Since he is typically a BIG fan of Black Gates ( as are everyone that i know that have tried them ), he might be able to help you along or at least offer suggestions. He might even be able to sell you the exact parts that you need. Sean

Yes, ask Stan Warren at 541-344-3696
He lives in Oregon. Best to try between 4pm and 7pm pacific time.

Finally after all this time, I just purchased ELNA SILMIC II 50V 100 UF radial caps and 4 VISHAY 40V 1000 uf axial caps.

Stan now suggests the Panasonic FM caps. The SILMIC II were judged better than either the Panasonic or the Blackgate caps @ Comparing electrolytic capacitors - May 2008 at high end audio by Eric Juaneda, and form other things I have read on the net, the SILMIC II seems like a great choice.

I got the VISHAY 40V 1000 uf axial caps because this is about the only axial cap I could find that was the right size peroid, they go on the power supply side so just replacing them because of age at Stans suggestion.

I also just purchased 2, 10k mono 24 stepped Attenuators to replace the volume pots. I got them cheap out of Hong Kong, off ebay

I also have some solid silver hook up wire that i will use to replace some of the more important internal wires.

I was thinking about by-passing the mute switch entirely, Just go directly from the Audio board to the line out jack.
still pondering this idea, any suggestions?

I am also replacing the 2, diode bridges with 6A 6 Amp 600V Bridge Rectifier GBPC606, Manufacturer: General Semiconductor
Part Number: GBBC606 THIS IS THE SQUARE ONE,

this will enable me to change the transformer.
I contacted fellow Agoner Thistlehd he has to date modded 3 Superphon Revelation Basics and was very helpful, he told me Stan says up to about a 220va transformer. (single is better than one for each channel)
AN2225 25v 200va 4.5”x2.3” Antek transformer is what Thistlehd used. he says its a Very nice upgrade, so thats the one I purchased.
also got some new RCA input jacks from tctubes.com

prob going to be doing the mod just after New years so I will report back when done
