Wife: Don't they make stereo stuff that doesn't need thingies that have to be replaced every week?
Me: The tubes in my (ahem) "stereo" don't have to be replaced every week, they last a very long time.
Wife: Then why do you have so many?
Me: Why do you have so many shoes?
Wife: You answered a question with a question.
Me: The question is the answer.
Wife: I'm going shopping.

My wife “A package arrived from Europe today?”
Me “Awesome must be the adaptors I ordered from Deyan”
My wife “You are such a geek.”
On that note adaptors are here which mean it’s time to test out some type 37 philco globes? balloons?
Only have about an hour on them. Definately some background hum independent of volume level. Gain doesn’t seem to be much of an issue. Normal listening levels about 12/46 with 6j5s. These seems to need about 16-18 to get to the same level. Both tubes are pretty microphonic but it seems to settle down the longer they are in. Hoping the hum will go away with some burn in time. The first thing that jumps out about these at first is a holographic staging. Second thing that stands out is some really nice decay not just on snare hits but also on bass guitar. I will try and get some pictures of internals later on tonight.
Yes, there is always that little inner voice that whispers: Buy them now! They always go up in price! It's a good investment!
Problem with me is that I don't mind buying, but I hate selling. Perhaps because of a couple of difficult buyers in NC in the past that gave me trouble...

Most Philco tubes of that era were manufactured by Sylvania. And I hope they will settle down for you. However, in my Glenn, 37's were always too noisy. I had better luck with 27's, but not much. lol

My type 37 experiment went much better with a pair of RCA radiotron.
These have black round plates while the Philco have mesh plates that make me think of 6c5.
A side by side. Similar internals but different plates.
Happy to report that the RCAs have no hum.

Most 'mesh', or perforated sheet metal, in tubes is some kind of screen, isn't it? Real mesh plates are quite rare if I'm not mistaken. The Philco up above has a genuine mesh plate while I think the Fivre 6C5GT, for example, has a perforated screen of some sort. It is usually called mesh plate anyway since we like mesh as it is cool.
