Completed the recap this evening after ordering a second round of caps that I missed on the last order. Smaller lytics have been replaced and the big can has been restuffed.
Brought it up on the dim bulb and even with it limiting to 22w and 50v while laying on its back with no external antenna in a absement it picked up KFBK Sacramento some 1500km away. I've heard stories of how superb Grundig's tuners were.
Unfortunately the fun was short lived and after a few seconds with the bulb bypassed there was smoke, sparks and the tuner died again.
R23 is a 1K 1/3 watt resistor as per the schematic. The original resistor was pretty cremated but I could identify the #1 brown and #2 black band so I ordered another and it burned up again. I can't tell what would be causing that resistor to burn up.
