The 706 has been with me for a long time. It was my second 706, the first was a MKII with only 2m. This is a fine rig, it has been mobile, but not beat up. I try to take care of my gear. No problems that I am aware of, I ran it mobile for HF and also VHF/UHF, so I put it through it's paces and haven't seen any problems in operation. Currently, it is in the shack for 2m/440. I always get good reports on the rig, it's just time to sell it to reorganize things. It is MARS mod'ed , as I used to be in MARS.
The amp isn't the one I was rebuilding, I actually sold that amp to Charlie, KT9D who converted it to running a pair of Russian GI7B's. This amp I bought with a few issues, like the meter shunt going out and the blocking caps aging. I used the power supply board from the ZC and replaced the meter shunts with some higher wattage resistors than original and replaced all the DC blocking caps. I had a brand new plate choke for the LK-500, so I also put that in while I was at it. I fashioned a piece of plexi glass into a divider between the tank circuit and tubes to force more air through the tube sockets and out the holes that had been drilled under the tube sockets. I really struggled with selling this amp, I have always liked the Amp Supply equipment and it has been a good amp that is easy to tune and holds up well. I just need to sell it and some other gear to reorganize between my mobile and shack.
John(KB9UDE), is bringing several items, some 800MHz commercial handhelds, a Yaesu FT10(I think) dual band mobile, and some used audio gear as well. Who knows what else he will dig out of the storage room!
