Looks great to me and it makes them so portable. I can plug in a 1.5m cable and it's go time.

Awesome, post a pic if you get a chance.

Received a Miyoo Mini Plus from my daughter at Christmas and been having a ton of fun with it. Tossed the stock 64GB card in the trash (pure junk), installed a Samsung EVO 128 GB, Onion OS and the Tiny Best Sets. Now I'm looking at handhelds from Retroid, Anbernic and AYN... 😂

My first guess would be the 3 feet of wire connecting the tube that's causing the hum. 😉

I was just thinking the same thing, those were great times!

Vaping leaves a film on things, but it's not anywhere as bad as tobacco smoke tar. So it's really all up to you. I can't see it hurting stuff, but I've never fogged out a room without some sort of ventilation going.

Dug out a blast from the past, the good old HohmTech Slice. Anyone remember this and the Hohm Wrecker G2? They were the only mods that could Temperature Control any wire and they actually did a very good job at it once you got the settings all tweaked and tuned.

Putting a tube in your freezer does NOT make it a cryo treated tube... :sweat_smile: Give this a read... https://www.effectrode.com/knowledge-base/cryogenic-treatment-of-tubes-an-engineers-perspective/

Considering the post is 13 years old and Head-Fi went through a major forum software change a few years back. I suspect it was lost in the conversion.

Looks like a ton of work for some questionable gains, but to each their own. :wink:

Since your not feeding into a DC power amp you should be fine. I would do as mordy suggests and resolder the pins on that tube.

Very generous offer! Would love to have them but there are others who would probably put them to better use. :beerchug:

I don't see any problem doing that with your spare amp.

I never plug my headphones in before turning it on, it is an OTL amplifier it doesn't need a load like transformer amps do. I power on the MK IV, let it warm up for 5 minutes then plug my headphones in. Increase the volume from zero and enjoy. When tuning the amp off I set the volume back to...

Does it blow the fuse with the tubes removed?
