[Hallicrafters] SX-101MK2 Resto

This is why I posted that the "Total Overhaul Kit" from 
Kiss-Electronic.com may be a VERY good thing for him and his Elmer's.

It will make life much easier.

The Brother Warrior/Ham that gave the one to me, set it on the 
Electronics bench at the University he works at.

It ran into an HP Frequency counter, and the TEK-5440 that he also gave 
me for 72 hours.

Since then I've had to replace ONE tube,, and had to replace the power 
cord, as it developed an intermittent.  The cord issue was *IN* the 
clamp strain relief.

They can, and are stable and accurate when allowed to warm up for a bit.

I always check mine with the BK 8505 counter.

I eventually replaced the 25/26 combo on the boatanchor position with the 606A. I also was able to snag the entire line of 608 HP generators, several duplicates of some models. Even have a stack of the HP 7+ GHz gems. The size / weight of these are waaay too much to buy on e-Pay, er eBay, but I was able to get them cheap with no shipping charges.
