Some relax by playing Angry Birds...

I relax by bending wires...

You're not the only one....some amazing work here:

Live music, of course. After all, this IS Austin.

Saw a TV show the other day where the host cracked that Austin was the only place where playing guitar in a band won't get you laid.

I play with my dogs. I refer to them my sanity. It's hard to be cranky around a dog that is deliriously happy to see you, plus tail wagging is funny.

So the real challenge comes with placing the components neater than this:


I'm satisfied:


The teflon isolated silver foil for ground between all sockets is not yet mounted on the module shown. The module is installed in my preamp and functional.

I've an issue with the tube placed in the center of the line stage. It starts to oscillate after several hours of playing music. Replacing the tube didn't solve the issue, replacing the leaded grid resistors with higher value 1206 SMD had a positive effect.

I do fear that the teflon tube sockets are no good in this wide band line stage. The teflon part of the tube socket is higher than a NOS Tektronix socket so the induction is unavoidable higher as the pin connector will be longer as well. So either I've to reduce the bandwidth of the line stage or I've to change the socket. Well, **** happens.

Neat wiring and RF don't always mix. The snag is that the devices don't know you only meant them to amplify audio, as they see lots of nice UHF resonators in the wiring. Low loss sockets can encourage instability too.

I take my mountain bike out for a thrashing, or play guitar.

Alternatively, I put on the slightly crackly Slowhand (Clapton) album I bought recently and forget everything but the performance happening in front of me.

Agreed, but my Clapton poison is "Just one Night"....which usually slides into Pink Floyd after half a dozen beers :P

The line stages is built as described by Allen Wright in the instructions for the RTP3D and only the mentioned tube cause oscillation and only after several hours of music. I'll fix it one or another way. :-)

I'll keep an eye out.

I usually shop for vinyl in charity shops - there's often a wide variety to pick from. I've found some as cheap as 50p each, though playback can be rather variable.

The top layout in post 14 appears to have a lowish inductance ground bus connected to the central spigot in each valveholder. The bottom layout does not.
