Tandy RealisticPZM mircophones

[P.M. van Nugteren]

I'm looking for a pair of TANDY pressure zone microphones (PZM). They're
very cheap about f100,- (Dutch guilders) ($50-60). There should be a
TANDY shop in Antwerp, Belgium. The only other info that I have about
them is that they tend to give a better S/N ratio when fed by one mono
12 V battery, They should give a sound comparable to Shure's PZMs (used
with 12V batt)

So Europe listers, does anyone know that shop (phone number, adress) or
knows where to get them?

Thanks,

Paul

PS: TANDY/realistic some connection with Radio shack?
