SPT Service Notes: January-February 1971

We only have a partial copy of the January-February 1971 issue of the Society of Photo-Technologists Service Notes. What we have from it is four circuit diagrams for electronic flash units that were made back in the early 1970s:

• Vivitar Flash (model unknown)

• Vivitar Speedlight 40 Flash

• Goldcrest SR-30 Flash

• Goldcrest SR-35 Flash

 

 

 

Please Note: In order to keep the site online, we are now asking $2.58 for each file download, except for tutorials written by members of the Learn Camera Repair Facebook Group, which are $1. After you complete the checkout process, you can log in to your customer account to download all the manuals you have paid for.

 

Price: $2.58

 

For the first five years that we operated this site, we were able to offer all of these manuals as free downloads. The site has gotten so large and popular that we are exceeding the limits of bandwidth and storage imposed by our web host. Please don't share these files; if we do not bring in enough revenue to pay to keep the site online, we will be forced to shut the site down. We've set the price low eough that it won't burden those who want to learn to repair cameras, while hopefully bringing in enough each month to keep the site open. We are not trying to make a profit from this.
