Re: Another DIY SS Amplifier with NVA Boards

Well, having attended the Rod Elliot school of power supply design and carried out his instructions, I’m listening to the results of my endeavours. This is the most music I've had in my room…ever 😀 It’s ridiculously good. More of the music has been let out of Richard’s boards and the results certain...

Re: Another DIY SS Amplifier with NVA Boards

More mods: I've redrawn the power supplies in a better format, as done by Rod Elliot, put the 10000uF slit foil Supertech caps on the input and driver stage supply and put a symmetrical RC filter across the output of the output stage supply because a different solid-state bloke on the internet sez. ...

Re: Another DIY SS Amplifier with NVA Boards

Little bit more work on the power supply today. With this amp being roughly 50Wpc into an 8 Ohm load, I had a look at Rod Elliots site https://sound-au.com/index.html among a few others and found that the general consensus is that 10000uF per rail is the minimum capacitance needed for a mono amp of ...

Re: Another DIY SS Amplifier with NVA Boards

Decided to put another wood fascia on the amp. On/off switch has been moved to the back in order to clean up the looks:

Re: Another DIY SS Amplifier with NVA Boards

12 months since I last posted on this thread. Have just increased the capacitance in the power supply feeding the output stage by adding 6800uF in parallel with the existing slit-foil, 10000uF. So now we have 16800uF of storage per phase on the power stages, plus 6800uF per phase on the input and dr...

Re: The reality of magazine reviews

I like to think that Bowie read that Diamond Dogs review in "Audio," turned into a soul boy, hooked up with Nile Rogers and his mates and came out with "Young Americans" and "Station To Station." :mrgreen:

Re: The reality of magazine reviews

It’s interesting to me that I can remember virtually word for word, parts of some of the record reviews in “Audio” magazine. No other hi-fi magazine since has had as much positive impact on my own philosophies about the hobby. This unlike the thoroughly negative impact from the 80s subjective mags, ...
