Browse the content of the threads in new Window  Thread: Single-stage Melquiades vs. DHT amps in Melquiades Amplifier  397 Replies 
If one dht is good, two must be better? I don't know. Some people like combining 6C45 etc with DHT, supposedly mixing the appealing qualities of each. Other people find that using a 6C45 (or other high-gm tube) with a 300B just makes a 300B sound...

Hi Romy,I think you may be struggling to get 10-12db of gain out of a spud amp (the term is a play on "one tuber").... May just about get it with 6C45.... remember you will be stepping down something like 12 to 18:1 on the OPT.best case: 10db require...

[quote user="Paul S"] Given speakers that can be driven dynamically by single stage amplification, there remain a host of issues, and among those issues is color.  Most compression drivers are color-challenged to begin with…[/quote] I would agr...

Browse the content of the threads in new Window  Thread: Single-stage Melquiades vs. DHT amps in Melquiades Amplifier  397 Replies 
I am interested that Romy has found some interest in DHT amplifiers. Many, many amp builders have used many, many tubes over the years, including many IHTs, triode-wired pentodes, etc. Japanese builders have used big transmitting pentodes driven i...

Hi Guy, I know what you mean; this phono stage really should not work well at all.  I mean, voltage doubler, 3 stages of 12ax7, feedback, cathode followers, garbage looking power supply shared tubes for stereo...mortifying isn't it!  These ...

[quote user="nl"] I have used Russian high-gm tubes like 6C45 in amps before, including single-stage designs very much like Romy's single-stage Milq. These have many attractions. However, in my experience it just didn't have the tone. Jim de Kort of ...
