I recently picked up a Motorola portable (large portable) and it's missing a tube. It's a 9pin job all the way over to the right side next to the filter cap. Anyone know what it is? Chaiss TS 275 Sam's 174-9 Trying to send pic but my attachment isn't working
Tnx

Looking at sam's 174-9, that's a 12BH7, a combination vert osc and output tube. If you need a copy, I'm going to scan a few others on Friday and I can do this one too.

That would be great! Haven't had a chance to dig one up. Something a little odd about it in that the chaiss is stamped 1949 on but the Sam's is from '52
Tnx
