This preamp needs no full introduction as it is one of the best tube dht preamps you can buy for its money so I’ll jump straight into the specifics. I’m the 3rd owner, the unit has had some TLC done to it. All resistors changed on the CCS boards, HT PSU etc where necessary. The cheap crappy CCS trimpots have been changed with US made Precision 10 turn 1k pots so forget about jumpy measurements with the default pots which are inaccurate. All electrolytic capacitors bypassed with poly and metalised films where necessary. Some boards cleaned up a bit but I’ll still be adding some final touches to
