Choke vs. 1k/25W resistor

Post by erigm »

Why did Ken choose to use a 1k/25W resistor instead of a choke? What are the sonic differences? Thanks!

I was wondering this too.

While we're on the subject, has anyone tried something besides the cheap xicon? Vishay has a really nice one that's housed in an aluminum heatsink. They also have a this one that looks cool ...

seemed more compressed sounding when I subbed a R for the choke in a Marshall once. Apparently some JCMs came w/a R instead of a choke (100 ohms 25W??). Maybe the overwattage is so it can survive tube failure? Not sure.

In general, using a resistor for the "choke" makes the tone a bit hairy or fuzzy. As you go over 100 ohms, you will also get some compression at higher volume levels due to screen sag.

By contrast, using an inductor for the choke sounds glassier and smoother. The top end is clearer.
