Re: Mofo

Interesting. Looks a bit more sophisticated than my setup.

Re: Mofo

Thanks Misty. It's a bit too smart to fit in in my play room, but I aspire to bring the rest of it up to a similar standard! I got the CPU cooler idea from Steve S. They're 12V powered from a small 12V SMPS with buck converters to wind the voltage down to reduce fan noise. They're running about 6V b...

Re: 45 SET

I guess to some extent even measuring off the published curves is a bit of a lottery as it depends on how close our actual valves conform to the averaged graphs?

Re: Mofo

Thanks Steve, I've been trying to make more of an effort to box stuff up the last year or so...

If you do want to get rid of that old radio I might be interested, always fancied the retro look but never had one.

Re: C3g Aikido Phono

Brill, thanks Phil, I've been able to work it out with your help. £2.69 for two nuts hurts though! :lol:

Re: 45 SET

Whilst surfing the waves I came across these monsters - 200uF 800VDC MKP PP caps for £14.38. Worth a try for a power supply perhaps?

Re: C3g Aikido Phono

Nuts. I bought a couple of these to switch the battery power on an off for the MC pre-preamps I'm playing with. https://www.mouser.co.uk/ProductDetail/E-Switch/100DP1T1B1M1QE?qs=qz1iJzlMsAe3OD3LOti%2F2g%3D%3D Turns out they don't come with a locking nut... I didn't check the detail cos they always c...

Re: 45 SET

I had a bit of a play with vtadiy.com's loadline calculator as it's easier than building spreadsheets like you Paul. https://www.vtadiy.com/loadline-calculators/loadline-calculator/#calculator The results are a little different from Paul's - it's based on Koren spice models. This is the 45 with 4k6 ...

Re: Mofo

One more as it wouldnt go on the last post. . 20231108_123753.jpg . Under £200 all in. I use it with bass drivers so it was interesting to hear it full range at Dave's. It does lose out to a SET in the mid and treble, but the bass is nice and clean. The 2A3 amp though... beautiful. All the wonder of...

Re: Mofo

The advice at B&Q was not to use a rattle can but furniture paint as they felt I'd get a better finish. 4 coats later, it's okay. From a distance. It doesn't seem to be particularly resilient though. . 20231102_125107.jpg . With cheapo magnetic computer vents to allow ventilation. . 20231102_125...

Re: Mofo

I took my MoFo (and D3a-2A3 SET) round to Bostod's earlier this morning, dodging the heavy rain. And I realised I never posted any photos of my "proper" build. There were a few MoFo threads at the time, I think this was the one I piggy backed, so I'll bung them here. This was a cheap build...

Re: 45 SET

Interesting stuff Paul. I woke up this morning thinking about a low voltage 26 direct coupled to 45, but this is a very different direction. I need to study reread your posts when I have a bit more time, but I don't have any 10k OPTs, only 5k, so might not be a goer anyway.
