Foreplay and Paramour under one roof.

I've been enjoying  this setup for a while

So many questions.  Is the headphone output from the 2A3's and output transformers, or just the foreplay part?    Any chance of some inside pics?

Outstanding!  That is beautiful.

What are the switches for?

Thank you
Inside is a real rats nest but it sounds fine. A lot of mods. Iron upgrade, tantalum resistors, Schottky bridge, all pio and film power supply caps, pio 2a3 cathode bypass caps, shunted volume control, Mundorf sio and Obbligato pio coupling caps, dc heaters on 12au7 and 12at7 tubes ac on 2a3. 12au7 replaced by 6cg7 (highly recommended)  Copper shielding to keep hum to minimum. I measure under 0.8mV AC on speaker terminals (Fluke 287).
Headphone jack is connected to trafo output 8 ohm parallel with 25 ohm resistor per channel to create 16 ohm impedance. I've tried direct connection to 16 ohm tap on transformer but I've decided to stay with 8 ohm tap. One switch on the front panel alternate between phones and speakers and another between speakers and 8 ohm resistor (mute). My headphones are Audeze LCD-2 50 ohm. I do my critical listening on headphones, speakers are for background music.
Btw Foreplay power supply and 6.3dc supply are in separate  chassis.

I think you win the PACKING PRIZE!  I have those white Polypropylene film caps with blue ends for my power supply caps in my Paramours.  Great buy for the buck.

I see Obbligato Black Polypropylene in Oil, lots of KK Teflons and the KK Brownies (using them to crossover a super tweeter now) and Mundorf Silver+??/Oil.  There are things I can't identify. 

You, sir, have made a bilvit.  As Dolly Parton describes herself, 10 pounds of mud in a 5 pound sack.

He he reminds me of a messy workbench, as long as YOU know where everything is thats all that matters

Thanks for sharing!

That's a lot of capacitance!
