thanks, I thought about putting miniture triodes inside the dead wd11 envelopes and I have put a fet and a red led inside a couple of 01As as well as once a 12ax7 parallel connected inside a 01A.
I should retest all my wd11 as I think not all are dead. The radiola is from my great grandmothers family which is also my wife’s great aunts family which we didn’t know 45 years ago when we got hitched so I would like to keep it for ever .
