I'd like to join too. I'm not absolutely sure but I should be able to make it. If i do come I will most likely be bringing a friend, this is okay right? I can bring an AMB Y2 dac, the cavalli compact tube hybrid and an HD650. What I am most interested in hearing are a B22, orthos, and stax. 

If the y2 output is crackly and the y1 output is fine combined with both the usb and optical being the same, it might be a bad solder joint on the y2 dac's left output pins. A few weeks after i built mine it started crackling in one channel and it turned out that there wasn't enough solder on...

I have this problem even with the stock cable. I just push it back in whenever it starts to get loose.

Pin 1/6 to SG is 90.5 and 90.7, The wire is 2 conductor +shield so the shield is the ground conductor.      EDIT: nvm, I had IR and IG reversed. My CTH works now and is playing sweet music

My CTH has been running for a few months and it worked perfectly except for a slight hiss. Today I tried to fix that by replacing the in and output wires with some shielded cable. When I turned it back on there was a loud hum. I tried multiple tubes and nothing changed. I've redone the initial...

Simply stunning

Aren't those pins supposed to be connected anyway? The traces both seem to lead to ground.

If you have some diy skill you could go for an AMB Gamma 2.  It can easily be built for your budget. Or you could commission one from a professional builder.

You are very generous giving away your in ears. I'm not really at home in the iem world. I mostly listen to headphones and speakers but I've been considering getting some high end iems for some time. The fx 500 seems very interesting as I like bass but some describe it as having overwhelming...

The Input is an 1/8" just below the headphone out. I had a 1/8" for the headphones too but I didn't want to risk someone plugging them in wrong. I also had a neutrik 1/4" locking jack but that would have been a squeeze. What you see at the back are the two switches, The red one is the heater and...

Here are some pics of my CTH I finished some time ago. It has an alps blue velvet pot, Wima coupling caps and I have an E82CC in there for the time being. The volume knob is solid bronze and was made by Vilts.        

You can find a lot of designs on zaphaudio.com and on htguide.

All is well. It turns out I had reversed the heater switch. What I thought was 12.6v was actually 6.3v. When I put it on 12.6v the tube started glowing faintly and all the voltages were correct. It is now playing sweet music. Thanks for your help.

measurements were with tube in. I double checked all components in the input stage and the only ones that were off were r7r and r7l which were both 8.8k when measured but they both say 1822f so the measurements are probably because they are in the circuit. everything else is correct. It could be...

TB+ to sg is 98.8v so it's okay

pin1 to sg measures 96.6v and pin6 to sg measures 97v

I just finished my CTH and when doing the setup everything checks out okay exept the voltage across pin 1 and 6 on the tube. I get -0.6 with the red probe on pin 1. I tried reflowing components but hasn't helped. I'm a bit lost here because I was very carefull with installing the right parts. 

When you want to add a new piece of equipment that isn't in a certain list (Headphone amps for example). you can only select from a database. You cannot put a product in when it's not in the database.  A lot of commercial gear is available but diy stuff for example is nowhere to be found. Is...
