Preamp tubes for the DC-5, positions etc.

[nodscene]

'ello!

So. Just bought a DC-5. Loving it. The previous owner said there were some nice preamp tubes in the amp. Had to look. Knowing less than I would want to about vacuum tube electronics, I added all the info I could get from the markings on the tubes. Maybe you could give me some points on what they are and in what position you would have them in. I would want the amp to open up a bit more, a bit more chime in the highs. Plus some extra warmth in the mids. Here is what I got:

All 12ax7
v1 Philips ECG (JAN 12ax7wa / 4147 USA / 8726 ACW)
v2 Fender (80-35-185-5 / LL(?)IGN / 013341 7025
v3 Philips ECG (JAN 12ax7wa / 34 67 /8726 ACW)
v4 Sovtek (??? Russia ??)
v5 RCA (70 25 USA / ???
v6 RCA (AET / 7025 USA / C8 25 ???)

Output tubes: Electro Harmonix 6L6 (Russian) which I would like to change to JJ's (or something else?)

Thank you for your time and insight

Kind regards
Karl

Found this on an old thread. (Quoted from user "John Phillips").

On the DC series, the tubes are:

V1 - first gain stages for both channels
V2 - second and third gain stages for the lead channel only
V3 - fourth gain stage for the lead channel and FX loop return stage
V4 - second and third gain stages for clean channel
V5 - reverb drive and recovery
V6 - phase inverter

(V1 is closest to the input jack.)

Hope this helps.
