Tube amplifier progress

The valve amplifier is coming together nicely, as most of it is over 40 years old I'm hunting through my parts to try to keep it vintage looking. Although it is a separate head the controls are on the top like a Vox so I can access them easily, putting them on the front only seems to make sense if it is up high on a huge speaker stack and I assure you it won't be! I'll keep you updated and maybe post a video once it's all working.
Hopefully at my next gig at Gary's Club I can play my own songs on my homemade guitars AND amp
Optional techie bit;
The chassis came from the remains of an Armstrong 127m stereo tuner/amplifier, it originally used ECL86 triode-pentode valves but these are hard to find and not as good as the EL84s pentodes which are found in most smaller British amps so I have rewired the holders for El84s and added a separate ECC83/12AX7 for the two triodes (Driver/phase splitter stage) Also I want to add a switchable EF86 pentode at the input try try and capture some of that VOX chime but I'll add that later.-The rectifier is solid state. THe whole thing should push out 10 watts in A class, I'm not too worried about distortion though a nice overdrive would be a plus.
