I have designed and serviced electronics for 50 years, from vacuum tubes to solid state. For vacuum tube testing I use the Weston 981 and the highly modified Heath TT-1. Rp means Reject Point figure and New/Design figure is directly related to published transconductance (Gm in mhos) figures by RCA or others. Take Gm figures with a grain of salt BTW. Returns: I normally only sell electronic parts like vacuum tubes, so it usually is not worth the effort to return if something is amiss such as a tube not working when it arrives (probably ship related). But I will always make it right with replacement tubes or refund or both.

Delivered in secured packaging. Works in my application. Not identical in appearance, not mentioned in ad, but does appear in the photo when viewed closely for details. As usual for Ebay purchases from the US, postage is a bit expensive and takes longer than a normal USPS delivery but considered in expectation.
