Solder

I need to buy some more solder and I’m thinking 40% lead, 0.5mm with active flux. But I’d be very interested to hear from more frequent slingers what your favourite solder is for through hole work, including specific brand / spec - ?

Soft start query

From what I’ve seen most soft start modules comprise an NTC and a relay that bypasses the NTC once the trafo is charged up as it were. My query is why is it preferable to bypass the NTC? I’m sure it will still offer some resistance once up to temperature, but enough to mean the PS caps are not kept ...

Re: Chokes for MoFo

Same sinks as I’ll be using Ed so I’ll be interested in your layout, although I’m favouring monoblocks given the size / weight.

Re: PS advice

So Nick my takeaway from your post is; don’t bother with the cap Mx, just use the SMPS, OR, use a linear PS. I’m guessing you’d favour the latter . . .

PS advice

I’m going to build a big MoFo and plan on using a pair of LRS-200-24 https://docs.rs-online.com/6f52/0900766b814e4214.pdf Some builders on DIYA have added a cap Mx such as this https://allo.com/sparky/capacitance-multiplier.html and a CRC. I understand the MoFo has very good PSRR, so my question is,...

Re: Chokes for MoFo

Phil / Ed, I noticed that the discount had not been applied properly by the supplier. This has now been corrected so the amount you should each have paid is £88. Send me your paypal address or bank details and I’ll refund the difference.

Quite possibly Phil. I’ve seen their sign umpteen times over the years and always thought they were a commercial radio station !

Re: Chokes for MoFo

As soon as we get to 5 pairs I’m ordering. Note that these are open frame - a bell cover is £3.50 extra. I can collect them but if you are any distance from Huddersfield there will obviously be postage as well.

So please copy and paste and add your name / quantity:

Ian: 2 pairs

Re: Chokes for MoFo

BTW, I have confirmed that the 3.5A rating is the continuous operating figure and not the saturation current. Very Big MoFo if you have the sinks for it :D

Not sure how to interpret that Ray - does it mean you are thinking about it?
