I guess if you are going to follow the purist route for TW then aluminum is the way to go, but I’m not going that way.
Who knows? it may make the amp sound like total garbage. Although I’m a pretty long way of from starting on it I needed some electronic parts so I started buying parts for the next build. I hate to pay shipping for just a couple of parts so I’ll add things into an order.
Robin, how do you like the OTS? I built one a little over a year ago and I love it. Have you gotten it dialed in and found the sweet spots?
