Marcel's scratch build AC15 based clone

[Guvna19]

As for the 'whining noises' from the better half I have that under control Guvna19... In the next few months She's getting a new sowing room, an en-suite and a kitchen makeover... Maybe it's all getting out of control...lol[/QUOTE]

no sowing room here but done the kitchen / bathroom thing last year and new car prior to that, and guess what, cant shake the noise....lol
must be some sciency hearing device we could all buy to fix it......just kidding....all good, cant really complain...out loud anyway

Wow! You must have done something really bad!

[Marcel]

You don't know the half of it Simon...lol

More metalwork... put extra holes for possible later modifications and experiments, and with some drilling and filing got the large hole for.the power transformer done. Then bolted on the sockets and the transformers.

Not your standard look for an amp head which is okay as it is unlikely to ever find itself in a performance on any real stage with a real audience...

Next up for work is the front and rear panels...

[Marcel]

Front and back panels drilled and assembled.

To stay with the VOX theme I found some chicken head knobs for all controls. For the time being and convenience using all Alpha pots on all controls.

Front will read - input A & B, gain, treble with bass underneath, master vol, vibrato/tremolo intensity with speed underneath, then a space for either a reverb level or top cut, and the power switch.
Rear is - IEC power in, main fuse, HT fuse, footswitch, speaker out A & B, and the speaker impedance selector.

Access inside is from underneath and is not as roomy as I'd like but I suppose I'll just have to cope...

nice work Marcel looks awesome

Thanks Wokka. The real 'rats nest' photos are yet to come...

I wanted to tidy up the transformer wires before I set this project aside for a few days while I work on the RCM-4F. Ended up wiring up all the 6.3VAC heater connections plus all the Mains 240VAC wiring. As this will have a solid state HT rectifier there was a spare 5.0/6.3VAC 2A output from the main transformer which has been pressed into service as the heater voltage for the output tubes instead of a rectifier tube. As it stands the output tube heaters will be floating but if hum in the finals manifests itself I can always retrofit a pair of 100 ohm resisters to ground so as balance them up.

As a side line I've decided to loom all cables with older school harnessing. The aim is to avoid using zippy ties on the entire project.

I look at that and think "I could do that" then I fall down laughing at my own joke.

Thats super neat and tidy.

Looks choice.
