Very wise! I think there might be an element of liability about any electrical equipment in terms of interference it produces or being a potential fire hazard. aka Legendary Collectibles :) Yes!- tubebuyer2020

1101 Audio custom crafted headphone amps
Thank you for taking a moment to list all of them. Yes, I have been buying some from Hifi Collective. Unfortunately, all of these places are capitalising on the dwindling supply to various degrees of greediness. No hate, though! It's a fair game and I would do the same. There was a time...- tubebuyer2020

@L0rdGwyn another noob question if you don't mind: when ordering PCBs are you forced to buy a small (e.g. 50) batch or do you have a way of getting just a few?- tubebuyer2020

@bcowen @Paladin79 any advice on "healing" microphonic tubes, if that's even possible (without lab equipment)? Considering getting some of those silicon rings.- tubebuyer2020

Could not find any cheap double-EMI-shielded cables. Plenty of double-shielded with the useless foil.- tubebuyer2020

Eufonika (Valve amps from Poland)
I did not request anything specific in terms of vol pot to be honest. I had a look at one of gut photos and it says "ALPS JAPAN 049G 10KA x 2". I guess "10KA x 2" means it's a stereo 10kOhm with an audio taper, and perhaps "049G" is some manufacturing date code as I could not google it. Not sure...- tubebuyer2020

Eufonika (Valve amps from Poland)
I have received a new amp about a week ago - latest Eufonika model named H5DS (H5 Dual-Selectable). It's a customised/new version of the well-known H5 with the following distinctive features: 1) Driver tube: 6V/12V heater voltage selection. 2) Driver tube: automatic bias/support of different...- tubebuyer2020

A different one on eBay: https://www.ebay.co.uk/itm/313689639119 Interesting that it comes with an early square-getter 6n5s and an early-ish Foton 6n8s - both more rare than typical 80s 6n13s and Reflector/Nevz 6n8s.- tubebuyer2020

Thank you for the explanation - I have a lot to learn! No, I am only starting with some audio effects for now - one step at a time. The adjustable bias amp is one of Garage1217 ones (schematic is here http://www.mediafire.com/file/06g72zyu2d32gp6/Sunrise_3.1_schematic.pdf/file).- tubebuyer2020

L0rdGwyn's DIY Audio
@L0rdGwyn are designs you are using all self-biasing? I was recently thinking of using a VU-meter for visualising transistor bias in a guitar pedal. It kind of works on a breadboard with a resistor in series, but I have concerns about precision and the idea in general. I also have a headphone...- tubebuyer2020

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.- tubebuyer2020
