With that. ASD assessment done.
If I thought the forms were hard. Having to relive in real time all the shit from the past year...... Yeah. Am fucking exhausted now.
But I am now officially diagnosed with the Tism!
And with that. Tis done!
Original power switch controls the power. Tuning indicator still moves the needle.
Little Bluetooth amp sits on a custom plate
Speakers are bolted to a wooden panel ready to be sorted properly!
Love having the laser working again >.>
Oh I need a front panel for a little amplifier?
Measure measure. Cutty cut! Done! ^_^
Rewiring the lights. Originally off the 6.3v for the valve filaments. I'm gonna be running it on 24V for the amp. So 2 12v in series should work.
Replacing a load of old rubber wires too. Because it's crumbling o.<
Testing the bluetooth amplifier and a couple sets of speakers with my customary track "Hearth's Shadow" from the outer wilds "The lost reels" soundtrack.
This one is particularly good as it starts with a nice acoustic guitar to pick up the mids and highs.... then slowly transitions into a /really/ complex descending phased bass drone with multiple frequencies going on.
If anything is going to destroy a set of speakers or an amplifier... it's /that/ part
One set of speakers couldn't do the bass despite moving the driver as hard as it could.....
The JBLs have just hit the 3A current limit on the PSU I'm using >.>
Maaaaay not be able to use those with this amplifier..... It smells..... warm >.>
They sound fucking epic though >.>
Well...
My heart is pounding a mile a minute o.<
it fucking windy here!!!!
Blew open one of the doors at the unit.....
One of the doors on the first floor (second floor for those watching in black and white)
One of the doors that has a latch, but no handle so is permanently in a closed state o.o
Either that or someone braved climbing the decking pallets outside and tried to open it with a screwdriver...... Then got crushed by the stuff I had leaning against said door >.>
Needless to say, there's now something screwed on to stop the door from opening o.o
@ret @philpem it fucking windy here!!!!

I have found the source of the shmoo!
Looks like the input transformer has gotten somewhat warm and dribbled out a mysterious black goo! Which is somewhat offensive..... /I/ am meant to be the Mysterious black Goo around here!!!
Anyway. The underside is somewhat messy. Being used to Mullard and Avo test equipment and Compton amplifiers (Which are a work of art!) This looks like someone was eating spaghetti and sneezed!...... Then set fire to it!
My job today is to hijack the power switch and internal illumination lines so that I can keep this thing as stock as possible.
I'm removing the internal speaker and associated audio transformer that has also "shat out its guts" and put in a modern bluetooth amplifier and pair of speakers.
The tuner/Amp chassis is entirely removable making servicing a breeze!
To the left is the mains transformer that provides 6.3v for the heaters, and "Fucking OW!" levels of voltage for the HT side of the tubes.
Next to that are the EZ40 rectifier to make the DC, and EL41 beam tetrodes being used as the push pull for the speaker, and the EBC41 Double diode triode (try saying THAT 5 times fast!) that's used as the phase inverter for the pull stage.
The guy at the front is another EBC41 which is the diode signal detector.
The final 2 valves are the ECH42 and EF41 that do the frequency changing and amplification respectively.
Then on the right are the plates used for the tuning itself
