Hmm, if you don't get bad feedback in the bass easily in your set up, get the 0.1uf FT-2.

Bad feedback in terms of simply bad, too much or lack of bass?
It's not that I am a fan of huge bass, but at the moment I wish it was a little more present.

If the bass becomes murky and slow when you turn up the volume.

Then the quest is not over. FT-2 is not for me. Spendors are rather slow. Is it the same when it comes to FT-1 and FT-3?

Yes, Teflon in aluminum tube. You can use 0.022uF//0.022u FT-1.

I could, if that doesn't promise murkyness in a lower region.

Default riaa boards finished!

Got the boards wired up (for the most part), attached. I've got R-loads yet to voice and install. The Tex-Caps need trimming; presently at 46.6 and 14.06 nF respectively. Trimmers will piggy-back Tex-Caps. C and R out will be directly soldered to output jack in chassis.

I decided to do mirrored layouts to leave room between the two RIAA boards for big PIO output caps and/or the Maximus Lightspeed attenuator. This keeps leads nice and short.

Speaking of output caps- I've got a selection. For all the teflon, some nice vintage PIO's might compliment well. I found these polystyrene caps at ham-fests a while back. Might give them a listen, too..

Next step is to power up, get some readings and look at signals on a scope.

-Kent

Air dielectric capacitor trimmers I guess. Things progress like clockwork. Nice.

Congratulations Kent, very very nice & neat work.

What are these small things to connect the components to the pcb?

Little through-hole eyelets; my local surplus place had them. I cut the tops to form a fork or "U". Easy to drop in/change/connect stuff without removing the board from chassis.
