If possible would you please explain phase splitting in layman’s terms or point me to a reference so I can read up on it? And how are SET amps different?Do all these tube benefits apply equally in both pre amp and power amp applications?Do hybrids compromise sound quality or do they offer benefits beyond efficiency that someone should consider?Thank you. This stuff is interesting but at times like this I wish I would have studied EE rather than ME.
This is a complex question, my opinion is don't buy a 300B amp, this is a expensive tube, much less these ANKs they use PCBs.Instead look EL34, KT66, KT88, KT150 amps as Dennis Head Inspire Fire Bottle, it accept all these tubes and use point to point wiring, you can order custom made amps from Dennis.
I check on eBay and Dennis has no items for sale. How do we get a hold of him?
The ANK kits (at least the 300B monoblocks) use PCBs only for the DC filament regulator. The rest of the circuitry, including the B+ supply and all audio circuits are point to point. That said, I think a well implemented PCB can work quite well and I wouldn't rule out a design just because it uses PCBs. In fact, for a novice building, it's likely a PCB implementation will provide more consistent results. I do agree that the 300B is an expensive tube, particularly for the better sounding tubes. But it is a robust tube that will likely last quite a long time and sounds excellent in a good implementation. The ANK C-Core transformers seem to be quite good, although top quality transformers from Hashimoto, Tango, Monolith, etc. might be a bit better.
I dont see any point to point wiring.They have an Transistor on that red square boad on the 2º image.Any way they will sound good for many music lovers for some years.
SET also SE Pentodes are Class A amps, the output tube conduct the signal 100% of the time.PP are Class B amps, each valve conducts the signal 50% of the time.The phase splitter tube cuts the signal in two halves and sends it to the two output valves. So Class AB amps dont apply here.I have a drawer that show this subject, I will post if I can found it.
Here's a decent explanation - https://www.youtube.com/watch?v=8KKhDG2GSvo
Thank you gentlemen.
Don't believe everything you read in this thread.Both of my push-pull amplifiers are class ab. In fact I have never seen any for stereo use that are class b, maybe some early PA amps.The phase splitting = irrepairable damage usually indicates someone stuck in the early years of p/p designs.Good and bad amplifiers exist in both categories.Which is better depends upon the speakers and the listener's ears.
Many AC members have the habit of stating their personal opinion as if it were fact, they dont even write IMO.
Some with limited experience and super high post counts.
