Replacing Conrad Johnson PV-10

Looking for recommendations in replacing Conrad Johnson PV-10.  It's been acting up.  Used to have to turn it on, then off, then on again to get both channels working...now only one channel is working regardless of what I do.  It may be time to say goodbye.  So, I'm starting here for suggestions.  Current setup is:

Enlightened Audio Designs T-1000 (transport)

Audio Alchemy Digital Decoding Engine V3.0 (DAC)

CJ PV-10 (preamp) 

Berning EA-2100 (amplifier)

Snell E-3 (speakers)

MIT MI-330 Plus (interconnects)

Kimber Kable 8TC (speaker cables)

Open to tube or solid state preamp and new or used.  Love my system, but just want it to work.  Ideal budget is below $2K.  Nearest dealer is several hours away, so want some help narrowing down options.  Any suggestions/thoughts would be very helpful.  Thanks!

See of Atma-Sphere would be willing to sort it out.

They used to do repairs/upgrades (not certain if they still do).

These are the chips I was referring to.   One for each channel.  Simple fix.

Only IC chip in that pre.   It's a simple reed relay. Channels are intermittent because there is one per channel and they are both flakey

Write the number of the chip down and note how many legs the chip has and that's the one you need.  It's near the rear panel , 2 of them next to each other.  

Looked like D1B12A on a stock photo.

Also, while you are in there, the voltage regulators get hot. Little transistor like things near the front panel.  I think in the PV 14 they realized they were doing too much and split into 2 voltages, but I digress.  A little heat sink with a dab of heat sink grease can increase longevity.
