Set up with a Victrola record player. Aux output from record & Bluetooth
Mine is driving a pair of small Klipsch book shelf speakers. Started with 50% volume knob and even with small Klipsch speakers I'm getting good volume! Clarity is good but bass is light sounding. Preparing to solder in some new parts, casoding the drivers, raising plate voltage and rolling in a better rectifier. Thank you for your great UTUBE VIDEOS!
You really need to do the mod and cascode that front end - 300B tubes need a much bigger swing to drive them correctly.
The main deal with cascoding the driver tube was to bring good bass to the party. The factory wiring simply and measurably can't create enough drive for a 300B tube, especially at the lower frequencies. It has nothing to do with the volume control pot etc. My Klipsch RP600M have plenty of bass when setup in the room right, they aren't the limiting factor either.
If you have never heard one of these amps after the driver mod, I can understand why you might think there is nothing missing. There absolutely is. All the folks who are blown away after doing these mods aren't all making it up.
True, but if bass is in the recording. I need to hear it. Bach’s Toccata is nothing without the bass :)
I don’t have any issues with lack of bass on mine. Mine is an early model, pre-Covid era unit, which had better quality parts though, before the component shortages became a problem for the manufacturer. It sounds fantastic and has excellent power, so I’ve not found a reason to do Skunkie’s mod. Mine also had an Alps Blue volume pot which I believe isn't the case with later models. My old SoundArtist rebranded A12 also had the Alps pot, so at some point they made a change. I did change the caps though, as it had those square blue X2 types. Back to the bass, your Klipsch bookshelf units won’t make much bass, so I doubt it’s an issue with the amp. Enjoy, these are great amps!
