Re: Yay! New toy

PCBs arrived today for my trial of using I2SoverUSB and piCorePlayer as a possible alternative to my Transporter as streaming source. https://i.ibb.co/Jx20tGD/IMG-20240516-151759.jpg The board is a variation on the one I did for an RTZ DAC I am putting together for a forum member. That one connected...

Re: Valve amplifier service

I have a KKnoon sig gen and it seems quite acceptable. Mine is the £120 one with the arbitrary signal function and PC connection but they also do this one which is basic but might do what you need? https://www.amazon.co.uk/KKnoon-1HZ-500KHZ-Functional-Generator-Triangle/dp/B09B76SRRK ps. It even has...

For the US number I used Voip.ms and for UK I use Voipfone. The phones I have are mapped to the multiple lines.

Re: Nothing In Particular

I had the same issue when going to full fibre a couple of years ago. I didn't want to use BT Hub as I have a pfSense and VLANs setup so wanted to keep on using my own system but the BT Hub is required to use their phones and existing phone number. So I just got my own Voip phones and use 3rd party V...

Re: RTZ SDM (DSD) DAC

I have just swapped over the I2SoverUSB's power to an LM7805 based local regulator. (Normally this power comes from via USB from the host) I have to say I do believe it is an improvement. In this case I am using a raspPi B+ running piCorePlayer so it's output may have been weak and potentially noisy...

Re: RTZ SDM (DSD) DAC

That’s a lot of separate supplies! I hope you don’t mind if I blatantly copy what you have done with the bits I’ve gathered together. Great idea mocking it up on a wooden board first – I was going to do something similar so I can A/B test different options with the RTZ as well as the RTZ against th...

Re: RTZ SDM (DSD) DAC

Latest DAC build coming along. https://i.ibb.co/vV6pYdz/IMG-20240423-173254.jpg This is a wine-box lash-up to test various power supply options and also the new interface board for the JLSounds I2SoverUSB to connect it directly onto the PCM2DSD and feed it with two separate supplies. Most of the reg...

Re: Another DAC Project

What rating are those transformers Ray?

Those Myrra ones seem to be better value than the Block ones, at least at Farnell.

All sounds to be a very positive development Tony. BTW did you see my PM on DIY Audio?
Yes I did thanks Ray.

Re: RTZ SDM (DSD) DAC

I've lost track of the permutations but I think so yes.

There is some talk of different capacitor values in the passive filter part but all that doesn't affect the actual pcb provided you use 0805 sized COG or PPS caps.

Latest filter board: https://i.ibb.co/KjZQhF1/IMG-20240404-094055.jpg For the keen eyed you might spot my blunder of 4 missing tracks from the outputs of the first stage op-amps. :shock: I was in too much of a hurry. :oops: Version 3 soon... However, it is sounding brilliant. This one is updated to ...

Re: Nothing In Particular

I feel for you (and you Mum) Phil. Very similar happened to my Mum.

I hope she gets prompt care and made comfortable.

All the best.

Re: RTZ SDM (DSD) DAC

More "experiments" on the RTZ DAC. This is an experimental filter board built to fit the RTZ DAC using the circuit published on DIYAudio by Bohrok2610 utilizing the opa1632 fully differential op-amps. https://i.ibb.co/jbDP6LM/IMG-20240311-115904.jpg I have installed it in my DAC: https://i...
