Heathkit Schematic Diagram

This webpage
is an archive copy of one that used to be at http://www.circuitarchive.co.uk/heath.htm.
This
page has been reassembled from my copy (saved when the site was live)
together with files retrieved from http://web.archive.org
and other resources. Many of the files here are just schematic diagrams
but some include additionai information such as specifications, and a
few are complete manuals.
Please DO
NOT contact me asking for circuit diagrams that are not listed, for better
quality diagrams, or for help with Heathkit equipment. Everything I have
is on this page, so any such emails will be ignored. However if you have
further diagrams or information to add please email - paul (at) vintage-radio
(dot) info
The Heathkit
schematics on this page are copyright ©
Heathkit and cannot be commercially reproduced. Many
thanks all those who have contributed schematics to the original site
and to Heath Educational Systems for allowing their
schematics to be displayed here.
Due to several
people trying to aggressively download the entire site in a manner that
shows no regard for other users, I have now implemented a download system
that requires a displayed code to be entered into a box before you can
download each file. I apologise for any inconvenience this causes.
