I am with Kehut and Beavis. I have owned the JD-100A and would suggest the stock mod with NOS Mullard CV4004. I have also heard the level 2 mod from Parts Connexion and would put my money on the stock unit and NOS tubes, IMO.
Kehut has done more tube rolling than I with this unit, so if you go that way, you would have some sound advice!
I would suggest contacting Wally (Underwoodwally) at www.underwoodhifi.com for a new JD-100A - super guy.
