Yup, I think I'll do dual mono with one toroid per channel. Then double up everything. Seems the V5 release gives the option to purchase everything I have been looking for. Super convenient.For this kind of power you might also want speaker protection boards for each channel.
Minus the soft start. Speaker protection is something else.It seems he has everything on there.
Transistors, amp boards, rectifier boards, speaker protection boards, t ground board, ground lift boards.
Any of the power supply boards will work. For class AB type amplifiers, you don't usually use resistors betwen capacitors. You can use those boards by just removing the resistors and replacing them with a piece of wire. Class AB type amplifiers usually have much better PSSR than Class A type amplifiers and don't need the additional filtering. Class A amplifiers have a constant current load on the power supply while Class AB type amplifiers have varying current load on the power supply.
If you write email with your requests to toroidy they will let you know shipping, price, options etc.I'm leaning towards dual mono in either 220 or 220 power. Decision will be made based on toroid availability. Toroidy doesn't even have an option to ship the US on their site currently.
I see Antek has two different types. AN which they say is for audio and then AS which has the primaries and secondaries shielded from one another. Is the noise from the lack of shield audible or really just a "nice to have"?
The Antek AS series is the audio grade.
With all due respect, you seem to be contradicting yourself which raises eyebrows - you mentioned to me you wanted value and asked for the parts cost, which I gave you for a economy IPS+EF3-4 OPS with 80V caps (so 64VDC rails). Now you’re talking about EF3-5 and dual mono transformers? That’s not Eco at all that’s deluxe. Also You seem to be rushing and demanding people answer you. Now rest assured we will answer any build questions, just sometimes it takes a couple days not in 5 minutes. If you’re not getting a response, take the time to search the thread and learn?
Read this slowly, all new builders - I said this build should take you a while, and that also means the planning for it.
I’m going to suggest you start with basics if this your first amplifier build. That would be the EF3-3 or -4, a hypex 63V SMPS, and the speaker protection boards offered in the GB. That way you don’t need soft starts, Tgnd would be optional and gndlift would be optional (can just use a bridge rectifier standalone). This still gives you a state of the art amplifier that will handle 2 ohm dips at reasonable volumes. And I’ve measured the hypex with Wolverine and it’s silent.
If you prefer Linear PSU, fine, but use a well regarded soft start and capacitor bank board to look after it - use the forum search function or google search diyaudio.com please. Go to aliexpress at your peril.
You’re welcome to do what you like just don’t say we didn’t tell you so if your a couple grand in and can’t make it work or blow the internal windings of an “audio grade” toroidal transformer.
Take your time - building AND planning.
