    Salas DCG3 preamp (line & headphone)

    Wrong place for that discussion, I think. :giggle:www.diyaudio.com/community/threads/help-with-w-one-ladder-relay-attenuator-remote-control.427834/#post-8028818 Patrick

    Overcurrent protection monitor for a direct bias amp

    Patrick Turner (RIP) had circuit schematics for this very purpose on his website. The complete mirror site is here https://atrad-audio.co.nz/turneraudio/www.turneraudio.com.au/index.html there are several examples under various projects.

    Patrick Found your creation in your fourth link, nice. Can you suggest a substitute for those Toshiba drivers, another out of production years ago mosfet.

    A Higher Voltage DIY Discrete Op Amp - In the Style of the DIY FE 2022

    If the half rail voltage does not exceed 40V, perhaps 2SK170 for the input LTP might give you more SNR ? Or 2x 2SK209 in parallel which are rated at 50V. BTW, R9 in the first schematics (R17 on KiCAD) will see 136W at power on. I hope it can survive on the long term. Patrick

    Group Buy - Very Simple Almost Universal Speaker Protection

    And if you would know of a simple, reliable method of filtering a 3V DC superimposed on a 100Vpp 40Hz sine wave in ms, I would be most interested as well. Even MCU based solutions are still using the same analogue RC filter for the purpose. https://sound-au.com/project111.htm Patrick

    Ribbon Unity Horn

    Hey Patrick, so you don't like any of the current commercial made HF lens? Or is just the pleasure to design something that nobody have ;) Like a designer custom made suit 😎

    The ABEC thread... (translated)

    I think there is just a technical problem. In the morning it was working again. Now the error came back. We should have patience.

    Help with W-One ladder relay attenuator remote control

    R15 and 31 are indeed 0r. Patrick quite possibly not. I am taking regulated 12v from the Salas In select and using 317 to drop to 7v. The trafo for all that isn't particularly big and it is obviously also doing the relays on the input board. Do I GND the encoder board using the standoff...

    Am in need of 2SK333-E or-F For SAE 202 Amplifier

    As far as I can tell, the device in post #2 is E grade. And they are in the US. Of course one can also use a matched pair of 2SK223E/F if space allows. Schematics and service manual available at : https://www.hifiengine.com/manual_library/sae/a202.shtml Patrick

    Depletion MosFET Buffer

    Thanks Patrick. The tube cad stuff is always good. The ones I built had a servo exactly like he shows. No particular use for them yet. Nice headphone project.
