    How do you like the Solen caps?

    I don't know. I don't have anything to compare them to.

    I'm not sure how much of a bottleneck the stock caps are, but the iron core inductors and cheap resistors aren't ideal.

    They tend towards the bright in the places I've tried them.

    Here is a Wyred 4 Sound, STI-500 integrated amplifier that I picked up recently. This is a later V1 model.

    23 torx screws to take off the cover! You have to really want to see inside!

    Inside are two separate B&O IcePower 500ASP modules, each rated at 250wpc into 8ohms and 550wpc into 4ohms.

    The back panel has two boards for input switching and volume attenuation. They advertise a true resistive ladder for the volume control, but all I see is a chip for volume control...maybe I'm missing something but that is a bit misleading if it only uses a chip for attenuation.

    Otherwise, nicely laid out. Nice quality parts on all the boards. Front panel only has the optical encoder dial, a few buttons and the display. It is connected to the back with a long ribbon cable that actually lets you move the panel completely off and to the rear without disconnecting.

    Should have kept mine, you don’t see Dodd gear for sale very often.

    Still a little **** with his attitude when I met him at RMAF, he had to have been having a bad day.

    Just pulled my Jeff Rowland Model 1 out of storage. I had it upgraded with the new front end boards a few years back. Still sounds great!!!

    Are those power supply fuses? Can't tell but if you're in the "better power cables sound better" group those should be upgraded. If you have any fuses in the output stage like that, they are sucking the life out an excellent amp!

    Good eye! Those are rail fuses...and they work well because they saved the amp from a naughty preamp!

    ^^^ I have no idea what that is?! :p I initially thought it was a TVC, but, nooooooo...

  • The photo was the underside of a switching panel that I built for my model train layout. I allows me to switch up to 20 turnouts and control the power to up to 20 different sections of the track. Here is a photo of the top and rear sections of the panel. The paint scheme is based upon the old Erie Lackawanna railroad colors.

    Outstanding!

    I am reminded of some manner of old folk (?) song my maternal grandfather used to "sing" (for lack of a better word)... something about "the Erie Lackawan'..."


    EDIT: Well... alrighty then... maybe it was Where Do You Work-a, John? ("On the Delaware Lackawan' ")... but maybe not. :p

    That said, I found this -- which ain't my grandfather's song... but it is quite cool (and a new find for me)! :)

    I was a train controller a thousand lifetimes ago. For the Soo Line. I just found my stuff from train dispatcher school in Minneapolis, which I kept for some reason. Very hard school, way more complex than I remember.
