Today marks five weeks since I hurt my ankle. And this morning I managed to do my full mile plus morning walk without any issues. My dog was happy about this as well. At 18 years old the definition of “walking it off” after such an injury meant maybe a day. I guess now over 40 years later “walking it off” means five weeks. Who knew?
But I’ve also made a slight deviation with the 6V6 Curly Maple amp.
Continue readingI 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.
Continue readingI keep referring to the new amplifier as the 6V6 “Curly Maple” Amplifier. But is it really?
Continue readingYesterday I auditioned some new reissue Tung-Sol 6L6GC STR tubes in the 6L6 “Spalted Alder” amp. I was quite surprised at the results.
Continue readingRemember 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.
Continue readingPlease 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 readingSo I’ve been thinking about my next amplifier project. And I thought I had made up my mind. Then things changed… again.
Continue readingI 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.
Continue readingIn 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.
Continue readingI 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.
Continue readingI’ve managed to make a little progress on the driver stage of the amplifier. And another project is coming along well.
Continue readingThis 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 readingToday 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.
Continue readingThe paint seemed to be good and hard this afternoon. So when I got a little free time, I decided to start assembly.
Continue readingI’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.
