[RRDXA] Tubes

[ON4WW_pandora]

Hi

Sri for the bandwidth, I know this is off topic. 

For a restoration project I am trying to obtain the following tubes (RCA or
different manufacturer):
6883B (matched pair, if not matched still ok, 2 or 4 pieces) or 8032A or
8552 equivalents.
Also looking for 2 pieces 12BY7A.

It is no problem to obtain these tubes in the States, but am trying to find
a European source.
(in Belgium, customs add the postage costs to the actual item cost and then
apply import tax to this amount - is this the same all over Europe? Strange
modus of operandi, if you ask me. It makes importing from the States even
more expensive than it already is)

I have been looking for a 'reflector' (such as this one, or
topband/contest/rfi etc. reflector) for tubes, did not find one at first
glance. Is there such a reflector?

Tnx es 73 - Mark - on4ww.
