[radio nut]

I had a thread a while back about my Apex radio. Most people thought it was a home brew but I really like it. The grid leak resistor was a glass tube with metal ends and it has a sticker on it. It should be 3 meg ohms and it tests at 7 meg.My tube book states that the 01a should have a grid leak resis. of 2-5 meg if I remember correctly. i put the correct value in but now I would like to find the correct style. Any ideas where I can find that syle resistor?
