BigRedX Posted September 27, 2007 Share Posted September 27, 2007 No pics... no amp... I'm sure bits on a bench would be pic worthy. Think of it as the equivalent of the raw wood shots at the beginning of a bass build. Quote Link to comment Share on other sites More sharing options...

[attachment=2495:PICT0029.JPG] The larger transformer is the mains one the smaller is the output transformer. There is a 12ax7 pre-amp/driver valve and a Mullard EL90 output valve which is part of the EL34, EL84 family and sounds great IMHO. The VT1-Purist-Pro is acting as the main pre-amp and will push the output stage into overdrive with ease. The finished amp will have a 400W SS power amp, DI and Line out, VT1 pre-amp, tone controls, valve blended Fx loop, valve compressor and tuner mute.

While trying to hold a strainght face: is there any reason for the massively long shafts for the control knobs? On the previous rack pre, I thought you used normal sized ones, with lots of wire connecting them to the main board, do you intend to mount then directly onot the boards this time?

I would also attach a silicone nangeflaglet to the output of the reverse cathode muffplate so that the inverse current can draw sufficient voltage from the cocktruss array. What do you reckon?

[/quote] Build update - note the EL90 power valve next to the output transformer. There is only one pre-amp valve fitted on this pic, 3 more to add. The 400W UcD module is on the back panel, the big black round thing is the transformer for it. [attachment=2541:PICT0035.JPG] Quote Link to comment Share on other sites More sharing options...

DHA Posted October 15, 2007 Share Posted October 15, 2007 Latest..... [attachment=2884:PICT0007.JPG] The paint job is a custom one as requested by Sug. The final production models will be silkscreened and have an input and output LED VU meter, all the other features will be the same. There will be a blue backlight showing one of the five valves via the vents. The footswitch controls the compressor and Fx blender off and on as well as the Tuner mute. The colour of the LEDs matches the knobs which are different for different functions, i.e. pre-amp is red, blender yellow, etc. Two of these are still available at the lower cost to BC members.
