Q for Jakob or anyone: Pultec PEQ1 and MEQ5

[Marik]

Jakob or anyone,

Is it possible to put PEQ1 and MEQ5 together and run with the same gain make-up sircuit? If yes, what would be the best way to do it?

 

[fum]

I see Marik thought of this before I did :grin:

There is a "big" commercial eq that uses a vacuum tube amp inbetween eq sections.

See the above thread. I asked this awhile back and the answer was no. The two circuits see different impedence at in/output and are very reactive.

I think you could do it with an isolation/make up stage between them though as CJ suggests.

i don't see the problem with building an extra line amp, once you've wound all of the inductors, built the psu and the case it doesn't see like that much extra work after all!

hey CJ would that EQ be so "big" its "massive"? as i rember it has three double triodes in each channel, so are these arranged as a triode stage after each eq band and a tube output amp? i remeber the input stage being solid state.
