Re: 7S14 7S11 SAMPLER bias QUESTION

Thanks for your answer Raymond,

I have studied 7S11 and 7S14 vertical blocs. Question is why 7S11 works without cells, and 7s14 need it. And if is possible to use 7s14 with the same scheme. 7s11 uses +-50 v to bias sampling bridge.

Regards

Miguel

Take a look at http://w140.com/tekwiki/wiki/7S14/Repairs and the 7S14
circuit diagram.
You have to read the doc of the 7S11 and the sampling plugins as well.

Note that the 7S14 is a complete horizontal and vertical sampling unit and the 7S11 is just a vertical plugin for the 7000 series *without* its own sampler.
To make use of the 7S11, you need a sampler like an S-4 or S-6. Logically, the floating batteries of the 7S14 are in the samplers but the S-x 'es live without a floating battery supply.
Have a look here as well: http://w140.com/tekwiki/wiki/7S11
