Bit the Bullet ... Don Sachs Model 2 Preamp
Don Sachs here..Tube life.. well it depends.  All tubes in every piece I build are run very conservatively and not pushed at all.   You should easily get many thousands of hours out of the 6SN7 types.  The KT88 in the power amp should go 2000+ hou... 
Supratek or Don Sachs - which way to go?
Geez...  I have not heard them..... typed too fast! 
Supratek or Don Sachs - which way to go?
Hi all,Don Sachs here.   I just want to clear something up.  Yes, you can buy a kit from Roy and build a great preamp.  I use the same board.  I suggested a number of improvements to that board and now kit builders can have them.  That said, my pr... 
Don Sach's pre amp
Hi all, I have modified the preamp to take a 6BY5 rectifier because it sounds better and you can source 6BY5 tubes for $12 or less. If you own one of my preamps and pay the return shipping I will modify it for you and provide a 6BY5 tube for $7... 
Don Sachs 2 vs. deHavilland Ultraverve 3
The par metal ones because they are in New Jersey and you can get most any sizes.  I don't think they manufacture there though, they just stock parts.  Maybe I am wrong.  Anyway, you can get a cheap case and then have cnc panels made for $125 or s... 
Don Sachs 2 vs. deHavilland Ultraverve 3
I have thought about it, but it would be low powered, probably el84 based or 6V6, and 15-19 watts/ch.   The problem is that I cannot fit the best line stage and the best power amp in any sort of smaller case so have thought about compromises that ... 
Don Sachs 2 vs. deHavilland Ultraverve 3
Hi All,A customer pointed out this thread to me.   I will just say that I have improved the line stage by about 10-15% in the past few months.   I have gone to a different output cap, a Polish made Duelund copy that is just mesmerizingly good.   A... 
Are there any $1500 tube preamps that that can compare with Tubes4hifi's SP14?
HiDon Sachs here.  I am not trying to sell anyone anything and don't want to violate any of those sorts of rules so I will give my opinion.  I have built and sold over 40 custom preamps built around the sp-14 board.  My opinion is that if you take... 
Seeking Suggestions on Preamp Upgrade (CJ, Aesthetix, EAR)
HIDon Sachs here.  I see I have been talked about.   I would love to build the OP a preamp, but he has an amplifier with a 15K input impedance.  I could certainly use a really large output capacitor value and drive that load, but it has been my ex... 
Review: Space-Tech Lab VP-1001 Tube amp
HiI think that Albert has a pretty strong following even if it isn't too large. I emailed a few people to check him out when I was considering his equipment and everyone felt that he had built them wonderful gear and had been a pleasure to deal wi... 
Jolida reliability? Anyone with comments?
Hi,My two cent's worth... I have had a modified Jolida JD-1000a integrated for a month that I bought on Audiogon from "underwoodwally". I biased it when I got it and just recently replaced the stock Chinese EL 34's with some Siemens ones so I have...
