Tim,
We’re not able to support these kinds of modifications.
Our support is focused on builds that follow our designs. Once a project moves into significant departures from the stock circuit, we can’t reliably advise on it or stand behind the outcome.
If you’d like to build the kit as designed, we’re happy to help. For heavily modified builds, you’ll get better traction in broader DIY audio communities.
Feel free to shoot me an email if you’d like to discuss further.
