Heyboer makes a Twin power transformer with an extra 6.3v tap to power your relays.
It is also capable of powering either a quad of 6L6s or EL34s.
Give them a call.

It is an aluminum chassis. .051 so it is pretty thin. PT is 10 pounds. OT is 7 pounds X 2. I will brace the transformer mounts with aluminum angle underneath. I have built dozens of chassis with a drill press and step bits. Since I have the cnc router I would like to use it for this. My smallest hol...

Is anyone using a cnc router to mill a chassis? I could use a few pointers. I have used mine to mill tag/turret boards in G10/FR4 with a little success. I needed 3 different size holes in the boards. I used a 1/16 end mill to cut .14, .093 and .125 holes. (#4 bolts, turrets and eyelets) The holes we...

I would like to use the Univalve to see if the tubes are functional before my return window expires.
I won't be running them very hard.

Can I use a KT150 in a Univalve without damaging either the tube or the amp?

I buried my dad back in September. He was 96. I was the executor of his estate. The disposition his possessions was pretty simple. He had a buttload of investments and insurance policies along with gold and silver. He started gifting the gold and silver to us about 10 years before his death. The inv...

Here are some of the shapes that I have gathered over the years.
My thanks to everyone who drew them originally.

Can someone start a sticky so we can all post our stencils here?
