London Power Pre-Amp

How does it sound? Can you post clips?

It sounds absolutely fantasic
Slooowly working on the power amp. My current set up is using the GT Dual 75 using KT88 for the Power.
I don't have clips but,
The clean channel is suppose to mimic the Fender clean tone which it does perfectly. Can't say much about the Z-Pre or the Marshall tone. I never owned either to compare it to. My guess it matches the tone. I would expect different tone attributes once the Power Amp is working through EL-84s.

Sounds great. I just purchased a couple of kits from KOC for an amp I just built (power scaling and active noise suppressor). I am now contemplating building an entire amp with LP kits later this year.

Update.

Here is a pic of the front of the 3 channel pre-amp.


I ran into the issue of adding another fuse on the secondary. Ended up putting the transformer below in a doggy bowl.

Big red circle around the added fuses.


The grounding scheme is from Valve Wizard. The bridge rectifier is 35A. (really big)



From Kevin O'COnnor book about Speaker builds, I build the speaker cabinet.



Another Build from Kevin's Kit is the EL84 Power Amp




New Build I am working on is the Bass Am using 50W of power.
Here, I have the S-PRE up and running.
