More and more instruments are becoming obsolete and are simply not availabe from suppliers. To enable those customers to have their "Old Faithful" instrument serviced, we have listed a number of obsolete items to act as a guide. In some cases it is still possible to repair some obsolete instruments, and even issue a certificate of calibration. Just because it appears in our list, it is by no means

certain that we can carry out any required repairs, as a lot depends on the fault and if we have any particular spare part. However it is still worth making an enquiry with us.
If you are looking for a manual for an old instrument, visit our downloads page, or send us an Email, we may be able to help.
