Well, after enjoying the 2P29L as part of the Mule preamp project, I decided it was worth building it so I can continue with my adventures on the DHT land. The 2P29L sounds so good that is worth having it as a standing preamp so here is my new version in progress. Thanks DHTRob for your inspiration using the IKEA chopping boards in a slightly different way I used them so far:
Simple and neat. The 2P29L were stripped out of their aluminiun cans. Naked as when we come to life. The gyrator boards are ready and tested. Just need to get the Rod Coleman regulators and complete the wiring.
Happy DIY audio!
