McIntosh MR78 upgrades?

I have an MR78 that's working well. 

I can bring it to Audio Classics, and for about a grand, get the power supply and audio section upgraded, and the tuner will be aligned. 

There's another shop, maybe 2 hrs from Audio Classics that does a power supply upgrade for $250, plus an alignment would be billed based on actual time on the bench. So let's say $350-$400. 

Is the audio section upgrade worth $600? Would be most interested to hear from people with Mac tuners that have had them modernized.

Kennythekey-
The MR71 looks great in that maple case. Is that a Mcab.com custom?

My later model is looking tired and shedding.
I like the look of the base instead of footers also.

Your RM modded 71 must sound amazing. My stock box plays great. It has been refreshed/NOS tubed. I have the RM mod on the wish list.

Kenny-

I believe you just want to fuss with the 2 audio output tubes-6BL8.

The others are what was used to ad/align to spec?

Once changed, adjustments are off?
