  1. As a historian, I can identify with this thread very closely. My first book was published in 2009, and the second in 2018. Each project took about five years. The amount of online info posted between those two projects amazed me. Much less working the microfilm for the second project. One thing I discovered that many libraries have subscriptions to newspaper and other databases, and you can access them if you have a library card. That was a big help. Some of these library licenses, alas, are only "educational" or "academic" ones. For instance, I was pleased to see my local library has access to the New York Times archive. I was disappointed to learn their license only covers issues up to 1919.
  2. I would address this to the Antique radio forums https://www.antiqueradios.com/forums/index.php I'm sure you are aware that the "electrodynamic" speakers of that time use the electromagnet of the speaker as a filter "choke" for the power supply. There are guys on that forum who have a lot of experience with these type of speakers.
  3. The last time I saw them on TV, the back up band was doing most of the playing, and I expect that will be true of their Jazz Fest appearance next year. IMO, the Stones (who I have seen live and grew up listening to a great deal) playing Jazz Fest is the final act of de-Jazzing Jazz Fest. Ain't Jazz Fest no more...
  4. Lizards like to cuddle for warmth. My sister had a friend that had an iguana, and it wanted to sit in my sister's lap whenever she visited. She had mixed feelings about that!

  6. Thanks Marvel, that mike looks sweet (water) but I am not conducting any interviews right now, andI think since digital recorders have matured, I probably would buy one if I need to interview again
  7. Thanks guys. Now I think it is the recorder since output with the built-in mike is highly variable, I just have no other recorders around to cross check. There's always the record built-in to computer if I really need it.
  8. Hi, I have a RS Boundary Mike (clone of Crown PZM) that I've used for many years. It uses a 357 coin battery. I replaced the battery, but the mike barely outputs anything. It has sat up for several years, so I replaced the battery but still almost nothing. It used to be so "hot" that I had to use an inline attenuator with my cassette recorder, for interviews. I *think* this is an electret mike. Do they lose their charge over time, and can they they be re-charged? TIA
  9. JL you are spot on, except...I'd like to keep the Tek going (if it's safe). I rarely need a scope these days but looking to retirement I'd like to keep the Tek available without concerns. If I had a '63 Lincoln (and I wish I did) I'd pay for a brake job if it needed it.
  10. I have a Tektronix 502A scope, all tubes. A battleship of its day. It still works fine except for one little issue. The front panel is 60 v above ground. I am not equipped to work on tube gear. Anyone have an idea how this is a happening? I have the tech manual for it. TIA!

  12. It might be. I asked the property manager and he didn't know. I'm not sure if there is a transformer on-site. I don't recall seeing a transformer vault or a transformer on a pad. when next there I will see if I can find where the incoming line terminates on the property. This is a fairly rural area and about two miles from the nearest highway. Thanks!
  13. For many years I've seen a two conductor set-up on power poles in northern California. The poles have a PG&E label. I know they're not DC. I am wondering why a single phase supply is being provided anywhere now. The label says "high voltage" but there is no indication of what that might be. Any ideas?
