    Thanks for that step by step with photos. Give me the confidence to do it on my own.

    Much appreciated!

    Same process will obviously apply to the VO-660, DS4-4-1000.

    Different sound entirely. The DS-4-4-1000 had a 1000 HP 606-SC engine, turbocharged. Made an entirely different noise than the prior plodding, normally aspirated De La Vergne model VO engines used in the VO-660 and VO-1000 units.
    I was just looking through the Baldwin book last night - Baldwin bought the turbo's from Alco!

    The Tsunami II decoders are selected based on prime mover manufacturer. For example the Alco version has all of the following prime movers on each decoder:
    539 non turbo
    539 turbo
    244 turbo
    251A i6
    251C v12
    251C v12 supercharged
    251C v12 Century series
    251C v16
    251F v16 supercharged

    Setting CV123 determines which prime mover you hear.

    Neat.
    All I was trying to point out was that a DS-4-4-1000 had a totally different sound than did a VO.
    The 606-SC engine in the DS-4-4-1000 delivered 1000 HP out of six cylinders thanks to the turbo, while the 1000 HP VO-1000 needed eight cylinders. The VO-660's (SLSF 60 & 61) only got 660 HP out of a six cylinder VO. Interestingly, the RPM's were all about the same.
