dissipation is current times voltage.
You get those from the schematic.
These will be quiescent dissipations and signal only adds a bit to these, except for output emitter resistors and Zobel and such that have very high signal currents..
It was just easier for me to spread the virtual sensors over the schematic in the sim and see the dissipation values instantly. 10 minutes work.
That was the idea 😉
I can't print the template in correct dimensions😕The template I posted was designed for those heat sinks. I have a milling machine, but I actually prefer to tap those heat sinks with a tap in a cordless drill. Very good quality extrusions. As long as you keep everything cool and clean, tapping is very easy.
When an A4 paper was used i ended up with 2 pages.
When an A3 paper was used the dimensions are not correct .😕
I had tried print<< actual size>> ,<<choose size by pdf>> e.t.c

You'll need to print on legal size paper (14 x 8.5) or two pages. The drawing is 12" long.

Exactly.

It's alive!

A full test coming soon, after some burning time.😉

Wow, that looks really nice! I like the modular approach. I am very tempted to build a channel pair.

I have lots in stock. They sound great in bench testing. Antek sent me the wrong transformers for mine back in April, and are still giving me the runaround, so I haven't been able to finish mine for proper testing yet.
Yes,this will be a very promising projectWow, that looks really nice! I like the modular approach. I am very tempted to build a channel pair.

Looking good Thimios! May I ask what transformer you are planning to use?
Thanks, Terry

I will be waiting to hear of your listening impressions.

Terry,my plan is for two mono amplifiers,i have two toroidals 2x35v/300va,if I had the money I would use 500va.I will be waiting to hear of your listening impressions.
Carl,from a little listening time using VFA IPS ONLY up to now...it is a wonderful amplifier!
Thimios, looking excellent!
It would be also interesting to know your listening impressions from X4 front-end section - rather unique one 😉
Carl, this is our flagship project - strongly recommend!

Thanks I will. I'll make a point to set some time aside this weekend and review the thread.Carl, this is our flagship project - strongly recommend!
Thanks I will. I'll make a point to set some time aside this weekend an review the thread.
Some info on the front-end options, etc. is available on the web site in my signature. Also see the first post in the thread - I have arranged an index there.
Of course Valery,i will do!Thimios, looking excellent!

Please give me some time😴
I started populating the X4 this morning and two of the little BC846BPN chips joined the birds. Most of the SMD parts are fairly easy to deal with but these little buggers are a real challenge. I think I'm going to buy one of those little heat guns for this. I was resisting SMD but I can see that I had better get used to them. Through hole parts are disappearing rapidly. Us DIY folks don't amount to enough business to warrant the continued production of them.
