Very neat! I like the comment about using paxolin for economy because it was hand. If you check out the price of paxolin from stock it would make your eyes water!! A good idea to make it universal - for some years I've made a habit to make a cradle for any radio I'm going to be working on for more than just a quick repair. I just use scraps of wood and metal - whatever is to hand - bits of angle iron, flat iron, MDF, chipboard etc. Certainly a 'universal' cradle has merit in that it would save having to make a new cradle for each radio.
I've attached one or two pics - one of a KB FB10 'Toaster' upended for cap replacement, another of a Stella 105U, (which is similar in curcuitry to a DAC90A but with more refinements, such as bulbs that actaully glow, a couple of thermistors etc, and finally, a Ferranti 054 which I'm restoring for a nephew. A friend of his was going to take that and a Pye Fenman1 to the tip, but passed them on to him. He's given me the Fenman1 as a 'reward' for my efforts in sprucing up the Ferranti for him. And what an effort! The maker's service sheet looked comprehensive, in that it ran to seven pages, but it has no underside view of the 'rats nest' chassis layout, so I had to trace each component from its value and the valve pins etc to which each is connected. Some of the Hunts caps were almost inaccesible between two tagstrips which are back to back, and wider at the base than the top, rather like a tent. I've added some pics of the chassis showing the progress to date. Afrer reforming the three smoothing caps, replacing several caps and a couple of out of spec resistors, and easing a seized cam which operates the FM tuning, the set works well. However, I'm awaiting a UK sourced NOS ECC83 for the VHF tuner, and a NOS Russian made EM80 magic eye - on of four I've bought on e-bay for £20, hopefully wending their way here from Siberia! It had a flimsy sigle insulated mains lead, restrained as usual by having a tight knot tied it it, so I've replaced that with a 3-core lead.
Hope that's of interest.
