That sounds like a very thorough and painstaking restoration Tony. The photos will be welcome. I get a bit confused with these sets but your reference to the HE-30 suggests you have the version with a horizontal tuning scale. I've referred to this in the past on a thread that Andrew responded to as well ie Trio 9R59 "Got At"... by SHORT WAVER 22/1/11 [p7]. As I understand it the D or DS designations refer to the version with the small round dial like the one I have or perhaps I'm just confused? I don't think I got a direct response back then
