I haven’t gotten the time to complete the testing on the Curly Maple yet, but I did receive a couple of tubes for which I’ve been waiting so I can try them in the new amp.

Musings on the New Amplifier
I keep referring to the new amplifier as the 6V6 “Curly Maple” Amplifier. But is it really?

Yesterday I auditioned some new reissue Tung-Sol 6L6GC STR tubes in the 6L6 “Spalted Alder” amp. I was quite surprised at the results.

Remember when I said that you can’t always get what you want? Well, it turns out you can. At least in this case. Especially if you are willing to shift some priorities.

Please read the post “That Didn’t Go Well!” before following the power supply change detailed in the later half of this post.
Sometimes a design which seems fine at first can later exhibit some marginal behavior. This exact issue recently reared its head with the design of the 6L6 “Spalted Alder” amplifier.
Continue readingThe Next Amp
So I’ve been thinking about my next amplifier project. And I thought I had made up my mind. Then things changed… again.
Continue reading6L6 SE-UL Top plate installed
I got a chance to do a little work on the amp today. I managed to install the top plate on the spalted alder chassis, install the filter inductors for the power stages, connect the output transformer secondaries to the speaker terminals, and wire in the power transformer primary and indicator light.

In the last few days I’ve managed to get most of the wiring on the 6L6 SE-UL top plate complete. This includes all the preposterously large power supply filter capacitors.

I got a little more done on the amp this afternoon. The grid and cathode circuits on both power stages are now wired and tied into the driver.

I’ve managed to make a little progress on the driver stage of the amplifier. And another project is coming along well.

This is just a quick post to let everyone know that I have made some progress on the subject amp’s wiring. Unfortunately, there is a complicating factor which is slowing me down.
Continue reading6L6 SE-UL Transformer Wiring
Today I took some time to install the signal ground bus and wire the transformers. But I also wanted to discuss a specific aspect of transformer wiring for the B+. I often get questions on this topic from people looking at the 6336 SET Amplifier. Let’s take a look.

The paint seemed to be good and hard this afternoon. So when I got a little free time, I decided to start assembly.
Continue reading6L6 SE-UL Gets Its First Wires
I’m still waiting for the top plate paint to harden. But that didn’t keep me from getting some wiring done on the chassis today.
Continue readingJumping the Gun
I know that I told myself I was going to give the paint on the 6L6 SE-UL top plate a week to harden before I started assembly. But then I thought “Hey there’s other assembly I could perform”. So that’s what I did.
