Pretty damn nice so far. Staying tuned

Beautiful work. A 300b build is definitely on my wish list. Following for sure-

 

[Yesterday]

Paper template to help cutout and drill holes (this weekend weather permitting)

Close-up of socket. Amphenol made in Chicago.

Done nothing for my 300b amp. As my son is coming home from England this weekeind. So had to finish this mediastreamer + headphone amp for him to take with.

 

[Yesterday]

Decided to try harder to make a drilling and cutting template.

Decided to use a different transformer for the 300b psu, since the other one had 400mA. And that's a little over the top...I'd prefer to use that for a 6c33c project.
Also sacrificed a shroud so that the power transformer is cradled by the off white...looks old school. I like it.

 

[Yesterday]

Drill drill drill.

Just insane how small the almost 4 inch wide power transformer looks next to the output enclosures.

Is that the front-end tranny? Are you putting one above and one below?

 

[Yesterday]

Its the 300b supply transformer 220mA.

The front end will each get own transformer.(60mA each) Also above.

Filament transformers for 300b and 2 Lundahl chokes for the output stage psu under.
