Left over parts from upgrades

[Alonzo]

What to do, what to do??  I have a ton of parts leftover from the 3+ Stereomours I have and have upgraded.  So put in an order to Mike L for some outputs and TA DA!  45 headphone amp with speaker outputs!  CLCRC (100uf/10H/100uf/360R/2.2uf) with BCP-15's and TL-404XL's.
Just a prototype for now, it's not much to look at and has some hum that is bothersome between songs.  Sounds great thru speakers though.  So, up next is to get a BOM for a cleaner version on a 12 x 12, maybe change input to a 10K:10K transformer and a P&G pot, DC heaters if I can't get the noise floor lower.
Pic's of the beat-up top plate and the backwards wiring attached for laughs.

Your wasting your time, better to part it out and sell me those 404's cheap

If you have filament voltage to burn i highly recommend you try Rod Colemans regulators, i have a 6A3/6B4G/6C4C amp mocked up using them as its perfectly quiet for headphone use.  I also have a couple of 245 tubes i am planning to try next so it may become a 45 rig in the end

The more I listen the more I love the 404's.  I have a pair in my Mainline amp, thinking about getting a pair to replace the EXO-145's in my main 45 amp.  So far they seem the top in my available outputs (404's then BH-5 Nickel's then EXO-45 tied with OT-2's).  If only Mike made them in Nickel or Cobalt.

I'll give the regulators a look, ordered the BH DC kit to see if it can be adapted, I have a couple 5v filaments unused to play with.

Just had a quick read of the Coleman reg manual, for a 45 tube he recommends a DC supply of 6.9-8.5 volts, 7.5volts being ideal.  If you rectify a 5v winding you should be good... http://lyrima.co.uk/dhtreg/dhtRegIntro.html

Which kit did you order, i noticed the Kaiju kit has regulators where the Stereomour does not.

I got the Stereomour II DC filament supply.  It doesn't work on the Stereomour I normally but I couldn't source a power transformer so I ended up with a Hammond that is loafing in this circuit. 
But I don't know, it's sounding pretty good now, I put a pair of 10uf 250v Dayton caps across the filaments.  Less hum and buzz, I'll have to judge when the kit come in if it's worth changing.
