Got in contact with Steve Mantz to get some old Hifonics amps refurbished/upgraded. There's a 20 dollar fee for any of the amps to upgrade/modify the Power supply. A 65 dollar fee for the larger amps to replace all the capacitors, 50 for the smaller amps. Then Burr-Brown upgrades are 45 bucks for a 4 channel, 15 for a 2 channel.
So, got an old Europa and Olympus VIII. Gonna pick up an Olympus VII, and a Zeus VIII.
Anyway, probably not gonna do anything to the Europa since whatever I do to it would just be 15 more bucks to do to a more BAMF amp like the Olympus. Does anyone think the Burr-Brown upgrades (I assume op-amps) would be worth the extra 105 it'd take to perform them on a pair of Olympuses and a Zeus? With that done I'm sure the amps could run 20 years without a problem, but would the Burr-Brown upgrades do anything worthwhile? Lower distortion, increase SNR ratio or anything else? I honestly have no idea what it means, I just don't wanna waste the money on something I literally have no idea about.
