Re: lathes

Sweeeet! I miss my sons not being at their Grammar School any more - I had access to all sorts of cool kit as the D&T teacher and I had an "agreement" which meant the big lathes, the CNC kit & laser cutters were all available... He rebuilt traction engines and stuff, so tended to b...

Re: lathes

I also have an MD65 with the BFE milling attachment. They're dead nice little lathes. Got mine locally to me about 15 years ago from a model engineering shop where the bloke was retiring. My only slight gripe is the 4" swing - it'd have been cool if you could drop out a bit of the bed like some...

Re: Falcon Heavy

Let’s not forget that if the SpaceX project goes as planned, and so far it’s done pretty well, it’ll be a hugely profitable enterprise. Elon Musk my be a dreamer and a visionary, but he’s also a hard nosed business man. He’s made enough to be able to afford to take huge risks funding projects which...

Re: Falcon Heavy

The embryos could be food I suppose. As for food for the spirit - I don't think so. I find it depressing and ridiculous. One extra madness doesn't get excused by the other things that are wrong on this planet. We'll have to agree to differ then. Plenty wrong with the planet - doesn't mean you can't...

I did say "some might question the validity of space travel when there are so many serious Earth-bound issues that could benefit from that level of funding." followed by: "However, I believe that his vision (or madness) is food for the human spirit – look forwards and up, not down&quo...

Re: Falcon Heavy

I certainly watched it (and the landing of the two boosters that made it back safely) Mankind-level visionaries are thin on the ground – some might question the validity of space travel when there are so many serious Earth-bound issues that could benefit from that level of funding. However, I believ...

Re: Discrete Op Amps used in a Phonostage

There are many breakout/carrier boards available to convert package formats. One caveat on these - they increase the inter-pin capacitances and can adversely affect the top end frequency response of the stage. Also, as mentioned, decoupling should be right up against the chip. With carrier boards, t...

Just the one 'plane? Very modest of you. What about the entourage?

Re: Discrete Op Amps used in a Phonostage

Also with the 797, make sure you have decoupling that matches the spec sheet, they are lively little buggers. And another also is to pay attention to the resistor values around the thing as you are in the place where the noise of 47R resistor matters. Very true - decoupling as per the datasheet - r...

Re: 2A3 "Pink SET" Amp Rebuild.

What about the dirt cheap Russian ones, the 6П6С / 6P6S (from Reflektor?) - supposed to be a 6V6GT equivalent. Cheers Nick, these would make a nice little addition to the tube roller's 6V6 stash. I have a couple of JJ 6V6S, from a time when I was messing with single-ended ultralinear Osram 6P25s an...

Re: Eggborough RIP

and you can swithch to a view of the data for France. I was quite surprised that, as I type this at just before 7am on a Sunday morning, overall demand for electricity in France is more than double that in the UK (60.9GW vs 29.6GW). The mix is very different too. That's because Les Roast Beef have ...
