Does anyone have some NOS Z561M tubes for sale or know of good website other than eBay to look for tubes?

[Zachary]

Hello,

In a previous post I was looking to buy multiple tubes but have since then I have been able to obtain everything I was looking for except the Z561M RFT. I can't find anything NOS (an not exorbitantly priced) on eBay and I'm not sure where else to look.

Write me and email if you have any for sale. I'm looking for one or two.

If anyone is curious, bellow is the clock I plan on making. It's tight but the tubes should (hopefully) fit.

Best regards,

Zachary
