And?

They were fine. Though that tells nothing about any other batches - especially the used ones.
I did wonder whether customs would check everything incoming for radioactivity just in case? Probably not.

They most certainly would if it meant they could collect more duty from you .

Tell me about it... "Handling fee"? I did not ask you to handle my stuff to begin with!

Postal services do check for radioactivity, I have heard of several cases of microscope equipment (old) failing. This turns out to be the coating material on the optics. The postal service will just not deal with it.

Thankfully, radioactivity did not stop USPS from delivering my vintage Pentax and Carl Zeiss radioactive coating lenses.

U contamination in the Barium coating I think

Did you hear that, @Ripper2860 ? Quit licking those lenses....for your own good.

Well repaired my first Melz today and success!
Thanks to @Paladin79 as a guide with my own tweaks I was able to get a nasty hum out of a 1956 Melz that started just after I started using it.
Whole process took about a half hour.

Hi,
I would like to replace my stock 6SN7 tubes with others. It will be difficult for me to go though 337 pages. What tubes do you recommend? I like warm holographic sound

 

[Deceneu808]

I feel like every 40s/50s tubes are warmish to some extent. What is your budget ?
My go to warm tube are GEC/mwt/Marconi B65 6SN7GT

Very nice solder work! Eventually Mr. Cowen will be able to do as well, as he practices on Fotons.
