I’ve been using these boards for many years now. Haven’t offered them as is required for anyone to be experienced well enough in SMD soldering to get these done effectively. I have a reflow oven so work at scale is easier this way. I’ve been doing a lot of SMD board design and building over the past few years though.
On a busy time regardless, I found the space to build these four commissioned boards for D3a drivers like the ones I used on my 300B amplifier. There seems to be a lot of interest and build work done around this design, so happy to see this happening.
Saweet
Definitely interested in 2 of them
Nice! What are the active/sand devices on this board?
The usual suspects in SMD version: LND150 for voltage reference and the ubiquotus IXTP08N100D2
Thanks.
I am using 3A5 tube connected in parallel as an input tube for my amplifier. Would be nice to try those. Bias is fixed and I run 9-10mA @ 95V.
This would work right?
Thanks
