Power Supply for Neurochrome 686

Does the Pope wear as silly hat?! . . . . . 

That's a yes btw . . . 

Guess that's end of thread then . . . haha.

Constantly (over here) . . . unfortunately.

Well, if I recall, you bought one direct from Tom?

If so, your space is greatly limited inside the case, so the one I have would be your best bet.

If i had more space, I'd have two traffos etc...bit I haven't.

Where does it say that??? lol

🤣🤣

Why is that there?

I can't see it on my page??

That's hilarious..... toxic masculinity on parade right there gents ..

Has that always been there?

🤣

Good lawd ..... I'll have to check the settings shortly

My understanding is dual mono is better on paper, in the real world not so much.

Either way I would still get the best traffo known to man, regardless of cost.

I think it's a surefire way of guaranteeing best possible performance, it's certainly going to be equal or better than the equivalent non duel mono design.

Not often you can do a side-by-side test of a dual mono and non design of exactly the same circuit though . . . . 

Thanks Martin, will have a good look at that. Likewise to much of it going over my head, but the important bits in layman's terms are in there too.

Of course circuit design and implementation is absolutely key but I think in general if the designer has gone to the trouble of making a more costly 'dual-mono' design in the first place, it is likely that component costs are less of a consideration and therefore they may choose to use the more expensive/better performing ancillaries (caps/J/MOS-fets etc). 

How much of the performance is directly down to using two traffo's as opposed to one, as I say is probably very difficult to measure or even speculate over, unless you have the two identical circuits, the only difference being one vs two transformers.

A well made transformer with FOUR independant windings is akin to having 4 transformers in the box. This is exactly how Angus (bonafide f@cking genius, no bullsh#t) told me to build mine, and is exactly how he is building his. I know whose advice i listen to.

Just to set a reminder here,

Chris has not got the space in his chassis to put 2x600va transformers in. The traffos may fit, but the required capacitance reservoir, Rectification, soft start and 2x speaker protection boards he will also require will make it impossible to build in to that case. 

That is why i opted for a custom-made transformer with 4 totally independent secondary windings.

There are still space issues, but this approach works really well and has been adopted by others who have the same amplifier. 

There wasnt that issue when we compared the soundstage of my upgraded 686 to your 2x SMPS286, IIRC?

Thats my point.....my single tranformer didn't give anything away.

That Traffo won't fit either.....the casework is very diminutive as he used SMPS with the ones he built.

Still a great looking Traffo though 😍😍

Tom is right BTW, as is Angus, and me by default 😁
