There are 3-4 excellent rebuilders on this forum that will do you proud, with pictures and results to prove it. Why wouldn't you consider them to do the work?

Do ALL of them. Don't cheap out or half-job it. Do the full blown mods and then you'll have NO 40 year old PL junk left in it.

If you get talked into keeping backplanes, that is your biggest mistake. Old wiring? Yer screwed. Old control board..... Holy shit.........

Replace all that shit and you'll own the last amp you'll ever need/want. THE BEST!!!!

I would consider having someone on the forum do the work,the advantage in my local tech is he lives next door-no shipping!!

A next door neighbor tech who's never seen a WOPL before will not put a worthy amp out until he's built a few. It's the little things. And quit worrying about $130 for shipping and insurance. If yer worried about that, stop and get a sony surround machine. Spend the money, it's the cheapest amp that will last you 30 years.

If you let Hexis22 do your upgrades, you will not only own a work of art - you will also have an amplifier that is better than anything currently available under $50,000. You will want to put that amplifier in your will and pass it down to the next generation if they value Made in USA value and the highest quality hand-made audio product capable of producing the most subtle sound attributes or generating Police-at-your-house levels of concert quality sound. Seriously, sign the blank check, take out a loan, or rob a bank. Best investment you will ever make.

Spitfun,
I agree with Mark 100%. I have completely WOPL'd (3) 700b's myself and they are second to none. Hexis 22's work speaks for itself.....first class artwork ! We have many talented builders on this site. As Mark stated above, the fully WOPL'd PL amplifiers are heirloom quality.

Spit, Hexis is a new addition, but hes not new to this type of work. Hes a fuckin artist with wire and solder. Seriously consider the man, there are no better that we've seen and that includes Gepetto....never thought I would EVER say that.
