6L6 SE-UL Performance Numbers
I spent some time this afternoon taking technical performance data on the new amp. Unsurprisingly, the technical data is in agreement with my impressions from the excellent listening session yesterday. This amp is a solid performer and just what I wanted from the design.

This morning I took a little time to complete the major wiring of the amplifier. Everything is in place except the B+ dropping resistor.
Continue reading6L6 SE-UL Top Plate Wiring Complete
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’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 readingSome day…
I suppose by now everyone is wondering what has happened to the 6L6 SE-UL amp project. Well, so am I. Kind of.
Continue reading6L6 SE-UL In the Black
So the black finish has set up and I think it looks far better than the grey. So, again, as long as there’s no uproarious outcry, I’ll be going with the black. I think this finish ties the whole project together much better than the grey would have done.
Continue reading6L6 SE-UL Grey and Black
As promised, after the primer was fully dry I took the power transformer down to my shop and put it together with the grey top on the chassis. Whereas the grey would make for an interesting look, I think I’ll like the black better. So unless there’s an uproarious outcry from the amp builders of the world, that’s the way I’ll be going.

Sorry about the title; I couldn’t resist. I got some time today so I applied the primer to the metal for the 6L6 SE-UL amp. The primer takes 24 hours to fully dry so tomorrow I’ll place it in the amp with an Edcor transformer on top and show everyone what the grey looks like with the spalted alder.
Continue reading6L6 SE-UL Chassis Finish Update
I now have five coats of oil on the amp chassis and the color is incredible. But this finish isn’t going to be like the last couple of projects. The wood is just too different.
Continue readingSpalted Alder – Notes on the Oil Finish
The second coat of oil went on the 6L6 SE-UL chassis this morning. The oil is bringing out something in the wood which was totally unexpected; color!
Continue reading6L6 SE-UL Raw Chassis is Complete
Today I finished putting the final shaping details on the 6L6 SE-UL spalted alder chassis. All it needs now is a final sanding and the oil finish.
Continue reading6L6 SE-UL Chassis Wood
Today I made my final decisions about which piece of wood would go in each position and orientation. This amp chassis is going to be a work of art!
Continue readingIt Happened Again!
I just got a notification from Edcor. The power transformer I ordered for the 6L6/KT88 SE-UL Amplifier on the 2nd of May (just 9 days ago) shipped today! I thought I was going to have a lot more time to get the spalted alder chassis into shape.
Continue reading6L6 SE-UL Chassis Decisions
Even though I’m waiting on a power transformer and some oversized components for the 6L6 SE-UL amp that doesn’t mean that all progress has come to a standstill. The new amp needs a chassis. And a new chassis means it’s lumber selection time.
