TS808 without IN- and OUTputBuffers

[Oliver]

Hello,

one of my next Projects will be a TS808 Clone.
In fact that i dont need a Buffer before or after one of my effects, i think of leaving that parts off the TS.
Will the TS sound anymore like a TS or will it kill that TS808Sound?

anybody tried that?

bye !

Jack Orman's Son of Screamer and the Barber Tone Pump are based on this idea and they both sound fantastic.

Hi,

Yes - the TubeReamer i heared the Soundfiles and was surprised from that good Sound..
I also thought of building one - so my decision is made :-)

thanx

I think the JRC4559 is used in the Barber tone pump, presumably because it has a high input impedance and low output impedance, eliminating the need for the buffers.

The output buffer can be a part of the sound.   The stock ts output buffer is an EF using a 10k emitter R the buffer is after the vol control so the output R stays constant at different vol levels.

If one uses a 2  opamp TS type circuit the Vol control is after the last opamp.  Whats different? With the vol at full there is no series R  to the output jack, with the vol turned down there is series resistance.

Series resistance into the first tube of some tube amps can make a different in the sound.  R.G.'s tech of the TS has a section about this.

If I was to build a two opamp TS I would try to use a 10K or less vol control.

FWIW I like a 100k vol pot on FF type circuit instead of the 500k
