    unbalanced/balanced to balanced tube input

    The group buy is the first one, cool that means it's the correct version. I was counting the tube pinouts counter clockwise. I'll try looking for a suitable buffer stage.

    unbalanced/balanced to balanced tube input

    Gonna build this from the group buy soon, On the board the silkscreen says "tube mounts on the back side of the board" but tracing the boards shows it's the same version as the one in first post. So tubes should be mounted from the top? I also have never built tube amps so I might be wrong. some questions I have: 1. How hot is the mosfet on PSU will be? Will heatsinking with chassis floor (3mm aluminum) suffice or does it need heatsink? 2. LT1085 require heatsinks or not? 3. Will it make a good preamp? Do I need to watch/match it's output impedance to the amp's input? 4. How to bias it?

    KG Balanced Dynahi build discussion thread

    Is there a probably some sort of hierarchy from best to less when it comes to THAT340, 2SK170/2SJ74, 2SA1349/2SC3381, 2SJ109/2SK389, and LSK489/LSJ689? Do they influence a lot or are the differences between each other minimal/negligible?

    DIY cable gallery

    I'm more interested with how they secure the wires. I've had some cheapo banana jacks in the past and they use grub screws. No bueno, feels like the wires will shear right off. This one looks good. Thanks!

    HiFiMAN Shangri-la Jr. Electrostatic Headphones

    My brother bought a gaming headphone once around 10 - 12 years ago and I found out that it was mono and only had the left channel wired to both earcups.

    How are the banana jacks? Do they make secure connection with the cables? PM me where you got them please.

    Sounds great, just let me know how much the shipping will be. Since I didn't order the TKD boards and pots you can send them out whenever after inspection.

    Holy shit 17% is disconcerting. I've been trying to search for that poll but my Google Fu isn't too strong. Mind sharing a link? Never mind, found it.

    And now what did you do TODAY?

    Moved to a new house yesterday. Rented a pickup truck since my stuff isn't a lot to justify a moving lorry service. I got some glass paneled TV rack so instead of covering the stuff with the tarp we used it to wrap the glass panels. Fucking bad decision. It rained like a motherfucker for around 10 minutes and although we managed to cover them with blankets and towels they were already wet. The blankets and towels helped a bit to channel and absorb the rain but, fuck man. What's done is done. Now laid out and leaving the electronics to dry. Speaker cabinets swelled. No fucking good at all. Most electronics were inside the passenger area, but the ones that were outside took some moisture. I'm just glad my Elac B5 has their original box, it kept them dry. Fucking, rain, man.
