Yamaha - E1010 Analog Delay  [schematic]

Here's a schematic I have of the rackmount Yamaha E1010 analog delay. It's split into two images and the resolution isn't the best. If anyone has a larger/ higher res. copy please post.

Nothing as unrewarding as posting something that is worth looking at and getting 0 response.

Thanks. I had these already but that's of no concern.
Comments?
Yes! Take a look at the LFO section for the modulation. At the end there's a hypertriangular conversion of the waveform. The 1010 was the first effect unit where I saw this put in practice.

Hypertriangular!?
Hammer.ampage.org and look for the Hypertriangular articles.

I did look. But I hardly see something I recognize well... Oh, yes, there are transistors! :blackeye :wink:

Any chance of higher resolution ones?

Now off I go googling for it... :wink:

I have one of these on the way. Any interest in gut shots?

Thanks a lot , very informative pics. I 've always thought this delay sounded terrific !

Guys, sorry for resurrecting this ancient thread. A buddy of mine has one of these in his possession and I think it sounds fabulous.
I was asked to make him a footswitch for it. Am I right (according to the schematic) that I can use a simple SPST latching footswitch connected through a mono jack?

Thanks!

Yep. Sure looks like it. It just mutes the signal going to the delay lines.
