I meant q5 and q6

Very nice. You have a perfectly working power supply and you've identified a key issue. That's great!

So, I have decided to just replace q5 and q6. I am also going to switch to the keratherm insulators. I am so tired of grease. Thus I will be waiting until the new parts come in before I go further. By the time I get done with this thing I may actually be qualified to build one.

I use Keratherm as well for the same reasons. Cleanliness and convenience.

Keep in mind that I don’t know any DIYer that hasn’t made a mistake or two at one point in time. It’s part of the hobby.

Tyer,

The next time you're ordering parts have a look at this. For a couple dollars it's been my best purchase in a while.

Hi all, I got my new transistors in today. I installed them and the keratherm insulators. I wrestled more with the LEDs. I am currently setting the bias on the second channel. The first went ver smoothly. I have 3 of 4 LEDs working. I’m not sure I care about the 4th one. I want to listen to this amp tonight.
It’s amazing how things work when you install the parts correctly.
Thanks to everyone for your help, virtual trouble shooting, and emotional support.

The only question I have left is would the Nutube preamp like this F5 and my frugal horns?

Im certain somewhere Mr Pass says its a good combination with F5.I guess helps tame F5 3H
