Thanks a lot for the comments. They mean a lot to me.
I really enjoyed building this.
The Beta 22 case is Par-Metal 20-16123N, with a DIY front panel and wood 'cheeks'
The rear area has been modified too, cut away to fit the Delrin (Or is ir Derlin?) the PLASTIC block that holds the IEC inlet and is part of the isolation setup for the power supply.
By the way there's a real sapphire set into the volume knob for the pointer dot.... it's only 2 mm but it's there. (REAL but lab-made, not mined.)
Lotta tubes in that Megatron. I'd like to build one maybe but boards are not available (last I heard) and I don't have the energy to organize a board run. For a casework feature on that baby you house the valves in Pyrex tubes cut to differing lengths like the ranks of pipes in an organ....
Lotta transformers in that thing, too, holy cow.
I gotta finish my DIY T-2. So many projects....
Alright I guess I will start to post pictures soon. I am working on a fully balanced Pass Labs F4. The goal is to try to fit two mono blocks into one chassis without it being so hot that it melts though my floor. So far I have built all the boards and have only snapped one 4-40 tap so I think I am looking in good shape . Pictures are on the way. I estimate this thing to weigh over 50lb and also hope that I can get it done in time for the bay area meet because I know that some people want to hook up their HE-6 to it.
Finally got around to finishing my HeadWatt. This is a design by Bruce Heron based on the 6DJ8. Vixr did the board layouts with some modifications by me. How does it sound? First of all, the amp is dead silent, even at full volume. After listening for a few hours with my Senn. HD600's, a few things stood out. Gershwin's "Rhapsody in Blue" on two pianos was fantastic as were all of the Janis Joplin I could throw at it. Chamber music also does very well with this amp. The amp falls off a bit and seems a little slow when there is a lot of bass as when playing Kodo. It still sounds good but the bass is just a bit weak. This was to be expected due to the smallish output transformers. Still have a bit of wire management.
One last thing, I have 2 extra sets of boards if any one is interested.
A couple of pictures:
Once i had the same task. It was so annoying and after 9 pm i was filing underneath my blanket because it was so loud. Allways buy a case with a pre cut for the IEC connector!
Some eBay cases come with pre-cut IEC inlets, however sometimes they could end up not matching the inlet you've chosen. Fortunately I have a CNC house where I can do all the holes I need on two panels for like 30EUR.
I was going to get one of those as it would have saved me the money to have to send it over to Front Pannel Express, but they didn't have one that was big enough or with XLR inputs.
Finally finished. Just biasing and burning in to do. First Watt F4. I put two monoblocks in one chassis. One monoblock per side. The advantage of this is that it is lighter overall than having two monoblocks, and I can choose between having many many different configurations. This will do 25Wx4 into 8ohms, 50Wx2 into 8ohms or even 100Wx2 into 8ohms. The disadvantage is that instead of having two big amps I now have one monsterous one that weighs enough to break my back.
This is a standard 12oz can for scale. Yes, it is monsterous.
Krell KSA-5 and Speakers are in the works. Stay tuned.
