Time for another Selmer PA 100! This amp was as most old British PA’s from the 60s and 70s an all tube amp with excellent transformers. Therefor they are a great platform for guitar projects and a bonus is that there’s room for a lot of controls on the big front panels. It has now become a two channel guitar amp with dual footswitchable master volumes and a tube buffered effects loop.

Here it is in original shape:

Taking out the old point to point board to make room for new ones:

These amps are more than often filled with 40 year old dust and dirt

So I prefer to clean them before working in them :)

It’s now a totally rebuilt amp with a new preamp, new power amp and new power supply section. It has two independent channels with gain, tightness, bass, middle, treble and volume. The mastersection has presence, punch and two switchable master volumes as well as a tube buffered loop.

Here’s a clip of it:
 
Super impressive. Man these sound sooo good. So much want! :cry: ! When can we expect your production amp??

Thanks man!

I'm working on another Selmer PA 100 at the moment, and after that I've two more amp projects in line before I will start building the first prototype.
 
I know I have said it before but your work is my favorite and the amps are killer and sound amazing! I love these threads!
 
I really enjoy these threads along with the build pictures. Thanks for sharing.
 
as usual, totally awesome. one day I will have one!!!!!!!!!!!!!!
 
Thank you guys! I'm working on the Selmer which has a more aged front panel now, it will become a three channel project.
 
Man I loved this whole thing but the saturation you dialed in at about 7:00 was just fantastic. Really nice work!
