Re: Entropy

This weekend entropy hit me. Wife and kids have been down with some flu thing all week so of course weekend was MY turn to feel carp. The shower is still playing up and the heating block had started leaking on it. Replaced that and it still shuts down after 3 minutes. Bother. So its probably the wat...

Re: Phono Transfer System Construction Information

The 150 likes low capacitance. Adding it will not help flatten things out. When I get this new preamp built that will be the first cartridge I experiment with to try and tally generator specs with end to end performance. If you look at the bottom graph you can see that the generator flattens out wit...

Re: Phono Transfer System Construction Information

Have clarified the spec and I don't have to handle the return from digital RIAA as that will go into another amp input, so I can use post RIAA gain on the analog path. Sweet. Boards in hand, time to order components :)

Re: Phono Transfer System Construction Information

well that is one of the things I want to investigate further. There is no accurate electromechanical model of an MM cartridge out there despite many attempts over the years. Thanks to Hans I now have some accurate electrical models so can hopefully extract the mechanical performance from that.

It really is 'I'm sorry Dave I can't let you do that' for real!

Re: Something to ponder about IoT

Lots of things for years have had really odd factory reset sequences though. I used to have a renault with a 'smart card' ignition. In most newish cars there is a button to disable the movement sensor in case you need to lock dog/kids/granny in the car for a short period. Not good enough for renault...

Re: Phono Transfer System Construction Information

Last time I tried messing with MC loading I nearly went mad so personally ignore it other than setting to manufacturers recommendation. And I don't change cartridges 4 times a day like he sometimes does. I am not going to offer him a 4 way option as that's just way too much soldering for me :D

Re: Justice: Gibson’s Bakery v. Oberlin College

I can never get over her name. Parents shouldn't be allowed to do that to their children! But not as bad as mr and mrs peacock, who called their son 'drew'. I kid you not. Littlest ones are only aware of one tv channel. I will keep it that way as long as possible. I had cable for 2 years in chicago ...

Re: Phono Transfer System Construction Information

I would agree. Problem is that he currently has an Ifi phono and he prefers 47k on all MCs on that. Explaining the function of loading isn't helping. But I will keep working on that.

Re: Phono Transfer System Construction Information

Phono 1 can feed either the Monitor or Record outputs flat or with EQ. IIRC Phono 2 can only feed the record output through the EQ though it can feed the Monitor output either Flat or with EQ. Depending on how you anticipate using it you might reverse the roles of the Record and Monitor outputs. I ...
