My fault - the T4 production is still not ready. We've run into various little detail issues with the cases. Then too, I've decided to offer different parafeed caps (Auricap XO). I've also developed a Pelican-like case that can be used for the amp. Because I think the pre-purchase folks deserve extra, I will make those things standard for them - along with the Mullard tubes. Believe it or not, I'm coming down to the final wire with this batch of 6. I actually hope to have them completed this weekend, assuming the Auricaps arrive in time.
