Hi,

Yes, I intended to direct RF leak in certain ways so that the RF will not bounce back and forth within a case.

Very neat looking, but lots of RF leaks.

RF from the outside will creep in where there's any gaps.

All NYAL OTLs use 6LF6 driving tube. Hard to find nowadays!

With silver color it would look great next to Bob2's turntable

Just realized I never got around to adding my turntable build.  It's a trimmed Lenco L75 with an aftermarket spindle and idler wheel.  The plinth is a combination of glulam and constrained-layer damping with a total of 4 Baltic Birch and 4 MDF layers.  The TransFi Terminator air bearing linear arm is for stereo--I have two wands, one for MM and one for MC.  The Pioneer PA-70 arm is a medium/high mass arm for a Miyajima Zero mono cartridge.

Great job ACHiPo! Looks very nice. Love the veneer!
The linear arm is working well?

Very interesting combination with linear arm! I wonder if you tried one cart with both arms and if there are noticeable differences.

Both arms are great.  The TransFi is amazing--really like everything I put on it.  I've only run the Zero on the Pioneer, but it sounds sublime.

I haven't done much A/B/A comparing.  The Pioneer sounds good with the cartridges I've put on it, but I've only tried medium to low compliance cartridges, which fit well with its mass.  The TransFi could probably do anything, but I haven't tried the Zero on it yet.

Finally at the point where there is hardware ready for prototype assembly... Spark-OEM power amplifier, fitting parts into the chassis.



And matching preamplifier, partly assembled... USPS was busy well past holidays and parts traveled to Serbia much longer than usual.

Spark-OEM, preamplifier assembly.
