Unfortuantely somebody 'sold' his parents (the youngsters Christmas
gift) at an excessive price a B and K Dynaquik 500, tube tester which
is not only somewhat used and very mouldy but also doesn't work!

When discovered not working the seller would not even make an partial
or full exchange for an A****er Kent the young man also had his eye
on.

Am therefore looking for somewhere to free-download a schematic. Have
tried BAMA and the mirror site, also Nostalgiaair. Unfortunately the
available schematics for other models (e.g. the 606) which I have
downloaded, are not same circuit.

Have you done any googling? There are a number of sites that are dedicated
to tube testers.

Some Model 500 manuals are available; but at a cost of up to $38 US
plus mailing it's rather expensive concerning an already overpriced
unit that may have a major problem such as dud meter!

The meter is really easy to check, set your ohmmeter to a high range,
and connect it to the meter's terminals. The B&K's meter should deflect
on one of the ohmmeter's ranges.


Any suggestions or other help would be warmly appreciated by both of
us.

If there is a more appropriate forum for posting this request I
apologise here for being 'Off Topic' and would appreciate direction.

This is a perfectly good forum to ask questions such as these.
