6em7

So yesterday I posted that the top plate was complete. Today I can say that the new spud amplifier is totally complete and ready for testing.

The wiring on the top plate for the 6EM7 “Bloodwood” Amplifier is essentially complete.

After several false starts, and a couple of minor reshufflings, The power supply side of the new amp is complete. Now it’s time to finish up the actual amp stages and get the top plate on the chassis.

I managed to get some time to perform the bulk of the chassis work on the new amp.

Just a quick note on the new project. Ten days ago I posted about how much trouble the wood gave me because of warps and twists in my plank of Bloodwood. Well, today I can say that it was well worth the effort.

Those paying attention to my post from May 9th already know I have a new project coming. This one is nothing new or Earth shaking. Just a slight performance upgrade to the 6EM7 Vertical Amp in a more traditional chassis.

I’ve been moving some amplifiers around today, listening to some that have been idle for a while and doing a little side-by-side comparison. And I’ve been reminded of a very important fact about amplifier performance.

This morning as I sat down in my office to check email and the like, I looked over at the amp in the corner of the room and made a snap decision. It was time to perform a SET swap.
