Nigel,

Have you ever identified a source for the faulty switches? I've emailed
ACAL, who represent Toyo and will wait to see what they have to say.

I've stripped down one unit - the one with all the biro marks as a trial
run. Have removed a couple of switches which appear to have no spring in
them. Can't see how they originally worked. Expected to see some sort of
spring to hold the switch out. By the way, a little bit of hob brite hob
cleaner gently applied cleaned the biro off without any detrimental effects.

Will keep you posted.

Rob

Subject: [time-nuts] FS Quantity 5 Takeda Riken TR5821 Frequency Counters

After a lifetime of collecting and hoarding I'm finally snowed under and
virtually unable to move, so I'm starting to have a long overdue major
clear out of surplus test gear and radio equipment.
Some is fully working and some definitely of "project" status and, if nobody
has any objections, I would like to offer some of the time/frequency related
items to other time-nuts before taking the usual route of heading  for Ebay.
 
Whilst it would be nice to minimise some of my losses the driving force is a
desperate need to clear some space, so hopefully I can offer some  good
deals along the way.
 
This first offer is for five Takeda Riken TR5821 frequency  counters,
offered as one lot, that came from a company closure  a couple of years ago
and comes more into the "project"  category.
 
Four are in need of a very good clean up, including removing some Biro marks
on some front panels, and three at least of those need some new switches,
similar to the classic Racal 1991/92 problem but at least in this case  no
more than six switches to deal with. One has a piece of cracked plastic
adjacent to the input B socket but a squirt of superglue or polystyrene
cement  should fix that.
The fifth is cleaner and, when recently tested anyway, fully  functional.
Internally all are  in excellent condition and I see no reason why all
should not clean up well and be fully functional if the faulty switches are
replaced.
Photos are on Photobucket, showing each counter in its own folder by serial
number....

I'm asking £50 for all five, including delivery to a UK mainland  address,
sorry but won't ship outside the UK on this one because of the weight,  and
other UK addresses might involve extra delivery costs.
 
Please contact me off list if interested, on a very much "first come first
served" basis.
 
A good quality scan of the manual is available for download, details of that
to follow.
 
Regards
