Jimmy,
I have yet to do this "t*******" on my Wonderbar. Radio book says: extend antenna to max, turn volumn to max, find a weak station near 1000 Kilocycles, then adjust "trimmer." Adjusting the trimmer means turning the trimmer' screw slot (looks like the head of a flat head screw) back and forth and the station will come in and fade out. Loudest station volumn is desirable. Trimmer in my case can be found below where the antenna cable is pluged into radio chassis. Yours I would guess is very likely in the same location. There are several holes nearby. The trimmer screw slot can be seen not very deep inside. Other holes seem to be just (vent?) holes. Hope this helps. Regards,
