Based on the PT I am assuming this is a 300B?
Which Hashimoto's are those and how do you like them ?

Just completed my TSE-II this afternoon after about two months of painstaking work. This all started out as a populated PC board on a temporary plywood chassis; it has since morphed into the form seen below, which was inspired by an Atomic Age (aka "Googie") -themed coffeehouse I frequent while on travel.

The chassis measures 12" x 12" x 4" on the outside (not counting the feet), and is constructed of curly maple, cherry, and 1/8" 6061-T6 aluminum plate. I paid strict attention to matching the grain on the corners of the maple box, and finished all of the woodwork with several coats of nitrocellulose lacquer. All fasteners are 18-8 stainless to eliminate the possibility of corrosion.

To make it easier on others in my household I installed an Arduino-based infrared remote control that drives an ALPS motorized volume pot. The power switch light is used as a status indicator; normally steady when the power is on, it flashes whenever the IR sensor receives a signal. The Arduino unit receives its power through a dedicated 5V regulated supply.

To make it easier on myself, I took advantage of some unused space on chassis side to install a complete set of tip jacks for CCS and bias adjustment (thanks to moggi1964 and kilokat7 for the nudge in that direction!). The jacks are recessed for a cleaner look, and they're covered for safety. Finally, I laced all of the wiring into cables - just for the heck of it. Covering all of this is a custom bottom plate with plenty of ventilation.

Thanks to George for such an incredible design. Of all the amps I've built over the years, this has easily become my absolute favorite. In fact, one of the reasons it took me two months to complete was that I couldn't stop listening long enough to get any work done!
Nice job mate.

Hi all here

Thought i've show some pictures of my ongoing buil.

I used some time to get the build "cooled" down
to my liking

I simply mounted som alu' bars & smalish sinks... The
fan is not really needed but good to have there for hot sommerday's
(when they come, if they do)...

Listening to it right now in livingroom...

I like the sound so far, marvelous 👍

More to come.

Rgds; Jesper

The pics are fine. It may be your download speed and youíre not staying on each image long enough.

Is your real name Mikkel Leicht? I wonder how you will move that thing to your listening area... A forklift maybe?
