Default autocad tip

...from a cad monkey - if you want to get rid of those diagonal face lines on your curved surfaces, toggle the value of DISPSILH. i can't remember if it's supposed to be 1 or 0...just set it to the one that it's not.

/andrew

ps - nice amp.

or maybe the command "solprof" and let the visible layer be black and the hidden lines layer be very light grey

faustian b., thanks...i tried "dispsilh 1" in the command line and it worked...removing the mesh lines in curved surfaces.

tobias s., I'll try your suggestion too andsee the effect.

i basically learned using cad by playing with it...although what i know now must be just the tip of the iceberg. I'm trying to learn rendering finishes on solids...any advice? how does layering work?

rendering in autocad, for me, can be tedious, especially if using texture maps. i still use trial and error for that. normally i just render with some standard solid colors - the textures never come out right for me.

[QUOTE]I plan to try running 2.8A bias per channel…if it gets too hot I’ll lower it.

Blue!! Did you manage to run your zen v4 with R0 at 0.47 ohms? More importantly, was there any improvement in sound quality?

When adjusting R4 (25Kohm pot), what voltage did you set your amp at? Did you get a regulated voltage of 42 volts?

I've finished building my twin block zen v4 and pretty sure i've over heatsinked it. I hope to post pictures soon but want to make these simple changes before posting.

Sad to say I haven't done much of the amp part yet...I will soon

Looking at your webpage...are your heatsinks one block of Al or was connected with one large Al plate. It looks like the latter judging from the silicon grease on the surfaces. With good surface contact, it will definitely be enough for 2.8A bias. You must have tried running them with 2A by now. What is the temp rise from ambient? From 1.5A bias to 2.8A, the difference will definitely be noticeable...from 2A, I'll let you find out...let me know . Increasing the bias of the buffer will do it good IMO...as Panelhead(?) found out...I'll do that too. Are you running 2 channels bridged? How did you wire this? Nice piece of work you have there, mate!

Heatsinks are connected to one large plate on each side. Don't have a temperature probe to measure how hot they are. Just only know that the heatsinks barely get warm.

Depending on the occasion, I would probably run them balanced all the time. Unless I bring one over to a friend's place that only has RCA gear - then each monobloc can be operated in 2 channel. Havn't worked out 2 channel bridge yet.

When you say you're running them balanced...how exactly did you wire them...is your circuit still the Zv4 circuit? Thanks!
