A new run of SSMH PCB kits is close to becoming a reality. PCB's have been ordered and Hammond Mfg is fabricating the cases. There will be 50 kits, period. No substitutions, no modifications, and no extra PCB's or other parts. BOM is the same as it's always been on the SSMH PCB website (with the exception of price). You'll get two tested 19J6 tubes with each kit, but if they are microphonic or go bad soon after, you may be on your own. I will have a handful of spares, if any. However, onesie-twosie's have always been available through reputable tube dealers and on ebay, although a bit expensive (typically $10 ea). I'm still acquiring parts, so I'm not sure of the final kit price, yet - perhaps $30 more than last time. Remember that the last time we sold these was around 2009! I will have the BOM corrected within the next week or two, so you'll be able to see.
They may go on-sale on Beezar in mid-November/Thanksgiving, I'm hoping.
