Modifying BAT VK-60s

Belden is a good wiring. I'm not familiar with capacitors inside BAT amps but "nothing special" to the coupling caps shouldn't realy mean you need to replace them. As to AudioNote caps you can find much cheaper solution but for now if I were satisfied with sound and reliability I wouldn't bother. As to cold solder joints seems quite strange to me and hear it the first time with BAT. Blowing fuses often caused by bad caps or bias-supply that is very complicated in VK60.

These sound like early version VK-60's, the fuses (one for each output tube) should been upgraded to 3A from 2.5A, as recommended by BAT. This would keep them from blowing when listening at high volume sessions.

I would have sent them to BAT, & saved $700.00!!!

Non-original owner or not, even if they are 8 years old, BAT may have upgraded them for free. They are pretty easy to deal with, & I would have called Geoffery Poor @ BAT first. They may have gone through them with a fine tooth comb & done all the upgrades for just the shipping expenses. There where many upgrades done between the 60, 60i, & 60se

Now that they have been Fondled by an Audio Repair Specialist, you may have to take them Mr. Goodwrench should any other problems arise???

That's just My Opinion, & GOOD LUCK w/ Them!!!
