Proud new owner of a Delta 88. This thing is ridiculous!!!! Blew me out of the water in 2 seconds flat!
Anybody know of any mods available by Dr.Z or anybody else?? This amp can only get better!!!
It's so bad it has nowhere to go but up? I bought a Dr. Z because it was perfect as delivered, not because it needed mods. If I wanted to buy an amp that needed help I would have bought something at guitar center. I would just play it. The docs amps are so sonically complex that it takes a while to get used to all the subtle nuances available without going in and messing the circuit up. Lots of modders have found, when messing with one of doc's creations, that the way he built it is the way it sounds the best. Doc isn't some hack, he REALLY understands what is going on in an amp and builds them to work together as a whole unit greater than the sum of the parts. Messing around in there is only going to make it sound worse.
What type of mods are you looking for? I'm not sure I would buy a new amp and start looking to mod it right away. I'm not saying you're wrong for wanting to do that, but I would at least put some time on the amp as is before looking to make changes, especially if you're already happy with the tone.
There is so much you can change with just your speaker selection. You don't need to go into the amp IMHO. If the speakers don't get you to where you want to be, play with some tubes. If that doesn't work, trade it for a different flavored Z. Your happy place is out there, the fun part is finding it.

If you want the amp to have much more clean headroom, perhaps to be used as a bass amp as and idea or a big clean amp that will have above KT-45 clean headroom change the 220K (I believe but do not remember for sure) plate resistors on the phase inverter to 100k. This will clean up the amp in trade for getting the stock amp's cool agressive tone at any level so to get an agressive tone you will have to really crank it higher.
Watch out though at high levels .... it may say "88" on the front of the amp but I have pulled 31.2 volts into 8 ohm load at 1 kHz with these amps with a solid state rectifier and this is 121.68 watts. Watch those speakers!
GuitarZ: Ugh! Dropped small nut while installing new outside lamp. Thought I saw where it landed. Couldn't find it. Moved the car & such. Engineering mind said, drop another (after ~hour). Bang! Within 5 seconds. Nut found! Yea! Wife Impressed!

GuitarZ: Best Pandemic Comment - Delivery guy shows up. As we're social distancing, I look at myself in brown loafers, black socks, gym shorts, t-shirt and say "I realize this is not my best look". His response "You can wear whatever you want to the apocalypse."
