Here's a table of the preamp pot values

It's a dream of mine to have a low output Dumble - for practical reasons Nik cannot make me a custom 1W job.

So I thought of going with a 12AU7 output section (single ended or push-pull)

A question please for you knowledgeable folk:

When Ceriatone made the OTS 20 they changed to a new preamp configuration.
Is that because the preamp from the 50W amp will not work nicely with a lower output power amp?

What further changes might I need to make in order for it to work with a 1W output power amp section

I wonder - on the Ceriatone Overtone amps, when PAB is engaged, is the entire tone stack bypassed? (i.e. all three - Bass, Mid and Treble?). 

I have a Ceriatone OTS Mini and a Volt (Made in UK) Dumble clone. On the Volt, when I engage PAB, the Mid control is still in circuit.  Apparently, the PAB disconnects part of the bass and treble controls and leaves the mid control in circuit, since the bass and treble controls have the biggest loading on the level.

Expert opinions deeply appreciated.

I wonder if this amp can be modded such that the one of the footswitch buttons also switches on Mid-Boost (in addition to activating preamp bypass PAB).

Clean channel: sounds lovely without mid-boost / PAB.

OD channel: sounds heavenly with both mid-boost and PAB activated.

I would therefore want the PAB button on the footswitch to simultaneously activate Mid-Boost and PAB.

Another option might be to use a 3 button footswitch (separate buttons for Clean/OD, PAB and Mid-Boost). But how would I wire the amp please?
