Ah. That was the hint I needed. Might be an Encore PT1025.

There were a few different models. The PT 1010 / 1020 and the PT 1015 / 1025. Probably just minor differences between them all but I've never looked closely.
Here are the Sams in pdf, which can be enlarged to view details:
Super helpful as I have one that is in need of repair and have wanted to find a schematic for them. Thank you!!

My most recent flea power build is this breadboard style SE UL EL34:
It uses a SMPS and has no soldered connections. Details here:

Build This Tube Amp With A Screwdriver
So a few years ago I picked up a Switch Mode Power Supply (SMPS) that's designed for tube circuits. It has separate outputs for 6.3v and 12.6v heaters and a 300v output for the B+. But other projects took precedence so it sat on the shelf for a long time. Some folks over at DIYAudio had...

What input tube is that?

Oh, @FlaCharlie : you are well advised to put in a cage... Who knows ? It may escape !
Very "Electrical Cabinet" wiring, that said...

"What input tube is that?"
At the time it was a WE 310B but I'm now using a WE 310A. No difference as far as I can tell.

So, I found the ideal opportunity to trade my Luxman SQ-N150 for the LX-380 though I had to drive to Cornwall NY to do it. It's American voltage, has a warrantee and I picked up at Hudson Valley Hi Fi in the above mentioned quaint little town along the Hudson River. The LX-380 is rated at 14 - 20 watts per channel at 1000Khz depending on the speaker load but realistically for full bandwidth 20Hz - 20Khz at 1% distortion its probably about 6 watts per channel. Still more than enough to make my Klipsch Heresy IVs go very loud if I wanted them to! An extremely nice sounding and elegantly crafted component.

Not sure of the exact output power but pretty sure it is below 10 watts. 11n7 driving 6ar6 triode.

My first thought was: "Is there an LCD under that octal base, as some folks install? No! (As I read further on). 
I don't think I ever posted a picture of my parallel feed 6V6 amp. I mentioned it earlier in this thread and included a link to another forum. It's just over 3W and uses a 6V6 as the driver with plate to plate feedback. Really nice and open sound and the FR is -3dB at 15Hz and 65kHz at 1W. Now working on a not-so-flea-watt SE amp at about 15W. Similar concept but GU50 and 6p15p tubes.

this is really cool. id luv to see a schematic for this amp--have you posted it in a build thread?
Making the Magnavox AMP-197 sing
I've made mention in a few other unrelated threads that I've been fooling with a single ended Magnavox amp, and promised I'd do a writeup once I was done. Well I am and this is that. First to set the stage, this amp came from here...
