As a follow-up to the reverb post, here's the schematic and layout I drew up for this chassis. There may be some mistakes, I haven't spent the time to double check it for the third time.
The idea is to use Steve Aloha's Tweed hot rod schematic plus add the ECL82 reverb. I'll use push pull pots for some of the switching.
Here's Steve's schematic

Re: Royale Reverb plan
What's up with the cathode follower into the tone stack? Usually CF is for a low impedence following stage. Does this help make the tone stack more effective?
Not a critique, just a dumb question.

That's from the Tweed Bassman 5F6-A. I prevents TS loading.skyboltone wrote:What's up with the cathode follower into the tone stack? Usually CF is for a low impedence following stage. Does this help make the tone stack more effective?

Re: Royale Reverb plan
That's gonna be a sweet amp, Bob. Based on the layout, I suspect you're going to have a real blues machine.

I'm thinking of using a Weber 50 watt Marshall OT. I'm having difficulty finding the right PT though. I's not a through the chassis mount so it needs to be a standup xformer. Suggestion?

Re: Royale Reverb plan
Bob, I used a standard horizontal mount transformer mounted on standoffs above the chassis deck with the wires led through a rubber grommet. Saved a bunch of real estate.Bob-I wrote: That's the plan....

Re: Royale Reverb plan
I was thinking of doing that, but I'm trying to avoid changes to this chassis, other than small holes for xformer mounting. It has 2 large holes for wires that I wanted to use.skyboltone wrote:Bob, I used a standard horizontal mount transformer mounted on standoffs above the chassis deck with the wires led through a rubber grommet.

Maybe a Marshall replacement. Thx
Re: Royale Reverb plan
I've seen Cathode resistors bypassed with capacitors but what's the affect of having a resistor in series with a bypass cap?

Re: Royale Reverb plan
The cutoff frequency of the ckt is a factor of resistance and capacitance. The series resistor reduces the effect of the cap.stoo wrote:I've seen Cathode resistors bypassed with capacitors but what's the affect of having a resistor in series with a bypass cap?
