Anyone tried Raytheon 5670 blackplates or GE 5 Star 5670 blackplates from the late 1950s in the Paradisea? I just purchased two pairs of these with original boxes.
Lots of different Raytheon 5670 out there.
Various constructions....various dates.
I bought a batch of 4 Raytheon singles.
None are identical, and there are subtle construction differences.
Two have yellow print on glass, two have red.
Three have black plates and D getters.
One has triple mica, the rest have double.
Date codes are only visible on red label ones, 1958 and 1964.
I have no other NOS 5670 types for comparsion, but these Raytheon
all sound good, and are better than the stock tube.
The one with grey plates/ double mica/ red printing/ windmill getter/ 1964 is very, very good.
Things just snapped into place with it. Sound is spacious, balanced, rich and musical,
yet still detailed.
They are still reasonably priced, so please guys, a little restraint!
Lets not get out of control with our bidding and sky the prices way
beyond reasonable levels...like I've seen happen with the WE 396A,
and the Bendix 2C51. No reason for it!
