Re: Smashed Plastic Vinyl Pressing Plant Opens in Chicago

I am impressed that at least one company has tried to make new presses not tied to 1950s tech. But they are braver than me. Dunno how much the new presses are but amortization calcs would scare me.

Re: Smashed Plastic Vinyl Pressing Plant Opens in Chicago

Whenever I read of another pressing plant opening I think of Tulips.

But with new vinyl releases selling for £20-£30 there is demand short term. I'd still rather have set up a brewery if I was young again :)

Re: entropy continued?

Progress. Made a new umblical up. Swore at infinity for using the shield for signal carrying and hooked a 9V battery to the standby line. Relay click, standby light goes out. Now can I find my stash of PP3 battery connectors anywhere? Nope. Ah well £2.50 gets me a box with a switch so come thursday ...

Re: A Low Noise Balanced Input Moving Coil Preamp Using the ZTX851

I think it's good enough as-is. We don't obsess over little things here which is why I avoid consumer-oriented fora altogether now. Particularly consumer-oriented fora discussing phono preamps... My Epiphany came when someone pointed out that, by the time you have added RIAA de-emphasis and A-weigh...

Re: A Low Noise Balanced Input Moving Coil Preamp Using the ZTX851

I was mulling this last night and the lowest output of the non-insane cartridges out there are 0.09mV and between 1.5R and 3R. I have one of these, current on long term loan to a cartridge and mulling getting one more as and when one pops up. Looking at your numbers I reckon you are still well below...

Re: A Low Noise Balanced Input Moving Coil Preamp Using the ZTX851

I did get a few for experimentation as I thought they might work in Richard Lee's common base headamp as well. But I will need more for some other things I now want to try. But a lifetime buy for me is only about a dozen depending on how many I need for matching pairs. It may end up cheaper for me t...

Re: A Low Noise Balanced Input Moving Coil Preamp Using the ZTX851

With my two lowest output carts that would give me 28dB margin running straight into the miniDSP inputs, but should be spot on if my friend ever gets around to delivering the TI PCM4222EVM he has promised. Handy. Noise looks good to me. We all love a phono stage noise drag racing w*nkfest. But for p...

Re: entropy continued?

Yes there is. That is my biggest worry as to what will happen if the glue has come loose and there is no feedback signal. Getting at it is non-trivial tho so have decided to risk it.

Re: entropy continued?

Although I dislike doing it, every so often I have to bodge and hope. Tonight was one of those nights. Wife and Kids out so I could get around to something that is hard to do with them in the house. In this case prepping my subwoofer ready to fire it up for the first time in >20 years. I bought it m...

Re: Affordable umblicals.

RS are still the same company as always, although they ate Allied to get a US base.

I still remember the joy of the new radio spares catalogue, when it was just one catalogue!
