- AMPHF - looking for a grid meter for a al811h
- Checking to see if anyone has a grid meter for a al811/al811h or if someone knows how to repair one that saw negative grid. Now the meter does not work but the voltage meter works so its not the diode d-16. I also changed the resistor that runs that meter which was open but still nothing. Thanks in advance.

- TUBES - For Sale: Econco 3CX300A7 (tests weak)
- I have an Econco 3CX3000A7 that I got in an estate sale. I sent it to Richardson Electronics in Florida to be tested and I’ve attached the test report.
I think I can only put up one picture so I thought the test report was most important. I have a photo of the actual tube with my QSL card and will send it to you if you contact me.
Per Richardson’s analysis, this is a good candidate for a rebuild. I am going to Hamvention this coming weekend and can deliver it to you there at no charge. Asking $150 or best offer.
