Although I've retired from vintage radios I noticed at Churchgate Auctions in Leicester a lot of equipment that members may be interested in. There are valve testers, full set of cards for the Mullard Tester, a lot of test equipment, boxes of valves etc and several radios. They don't have an online bidding system but you can contact them and leave a comission bid as long as you don't mind driving over to collect. This auction also has a vast array of vintage computer items. You can view a video on youtube and see the lot list by going to their auction diary. Hope it helps some of you
