And dont forget a very helpful tool for turning on and off...

Mindutis: yes. Switches requiring brute tactile force make them feel solid. :-)

Update about the bias: the Shuguangs were running at an OK level from the factory. The plate voltage was 401 V and the cathode currents were L: 52 mA and R: 53 mA - giving a a value of > 21 W which seemed high to me but the specs claim a max 30 W for Shuguangs - so it was exactly 70%. Tested a lower level and adjusted both to 40 mA giving a 412 V and thus 16.5 W. Seems enough for me (sound is the same) and maybe get a better life for the tubes?

I love it!

A recent build of Bruce Heran's Poddwatt......

6N1P drivers, EL84 (6P14P-EV) outputs.
Heath SA-2 OTs.
Power transformer was something I had on the shelf, but was a bit small, so I added a filament transformer.

Cherry knob and end plates.

Console pull was a Canadian RCA Victor with a voltage doubler power supply. Initially I thought I would be able to use the old can caps, but the hum level was too high, so I stacked some new caps under the deck. I left the smaller cans in place, disconnected.

The chassis wasn't really suitable for leaving exposed, so I built a wooden case - open backed.
Box is finger-jointed black cherry with spalted arbutus sawn veneer faceplate.

The chassis is raised about 1/4 inch so that there is good air flow via the bottom gap and the numerous perforations in the chassis top.

Good work. I like the bit of timber.

Console pull - made in Port Moody,BC by Chisholm.

The IEC power entry fit (with some work) into the hole left by the octal socket which communicated with the tuner & control panel in the console.
I used the original tube sockets which were fairly good quality. Desoldering the (very well-done) original construction was a bit of work. Usually the final lug on the tube socket is the one that breaks. Either my technique is improving or I'm getting lucky: this time everything survived.

End plates are curly arbutus.

How do you like that soundwize?

It sounds good, but in retrospect seems a lot of work for the modest power output it develops (~2 watts). I need to get some more measurements to try to figure out why my build isn't developing more power.
