I used to have a Matchless DC30 and sold it about 10 years ago. I toured with that one for a few years. Also, I've been repairing and modding amps for years for myself. I decided it was time to go back to the DC30. So, I ordered a Chassis from Nik and used the layout from March 12. I ordered all of the parts here in the US. I used some good parts (sprague, Mallory, CC resistors, etc). Built the whole thing myself. I used Classictone transformers. (I tried to get TDS but I think they are out of business now) Anyway, I'm really glad I went with Classictone. They sound amazing. Here is a video of my first fire up of the amp. I'm playing with a boss DD5 delay and a blues driver. I have an 18 year old custom shop strat with SD little 59s in it. I'll do some more videos soon actually playing and not just strumming chords.
