Channel 1:

IC MoD:
- Replace ic's u101 and u110 with gold contact ic sockets and change the chips to: lt1358, opa2132, opa2134, or LME49860NA (My fav)
- Replace u103 with that 2180AL08-U (lift pin 4, pin 4 should not connect to anything)
- Repeat for channels 2-8 (part numbers are the same except for the first number which is the channel number)

Capacitor/resistor MoD: Take a look at this pic for part locations: HERE:
- Replace c103, 107, 108, 109, 110, and 120 with 22u 35v bipolar caps
- Bypass those caps with .22u film caps
- Replace r117 and r119 with a 47 ohm metal film resistor
- Replace r106 with a 1k metal film resistor
- Replace r105 and r113 with a 15k metal film resistor
- Replace r114 and r115 with a 20k metal film resistor
- Repeat for channels 2-8 (part numbers are the same except for the first number which is the channel number)

PSU MoD: - Change the diodes to Fast (UF) diodes
- Bypass c8, c10, c24, c25, c36, and c50 with .1uf film caps
