Hi all - I have been considering (once I get the PCB to behave) using a LND 7317 SI-8 (CI-8), or SBT-11A pancake tube... I hear the 7317 is the best (http://www.lndinc.com/products/17/), and the SBT-11 (http://www.sovtube.com/en/x-ray-and-gei ... bt-11.html) is the best for the money at half the cost of an LND 7317... and the CI-8/SI-8 is also very good (http://www.sovtube.com/en/x-ray-and-gei ... ci-8b.html)

Anyone try - successfully or not - to use this ort of mica windowed-pancake tube? Any gotchyas or issues, recommendations, or keys to attaching? (I guess don't use long leads back to the counter, according to other threads)...

any help appreciated!

I have not used a pancake tube with the kit. I have tested an LND-712- it worked fine and has a mica window.

LND 7317 is a 500V tube, it should work.
SBT-11A should work
SI-8B should work

Try them and report back!

Having gotten ahold of one of those Atomic Dave pancake mounting kits at eBay: http://www.ebay.com/itm/221258613381?ss ... 1439.l2649

I see it came with a 4.7-MOhm resistor for the anode... looking around it seems some kits don't need the resistor, some do - would it be correct to put this resistor at the Anode of my pancake in this kit? Or skip it?

Many thanks,
Paul

The kit already includes a 4.7M anode resistor on the PCB (R2). You shouldn't need to add an additional external resistor, but it's likely that the kit will work with or without it.
