SET pre-amplification?

Thanks for sharing.

Did you provide some sort of low impedance load at the output (e.g., 8 or 16 ohms), to prevent the possibility of damage to the output transformer and/or output tube from inductive kickback in the transformer?

Can you share with us how you converted a SET amp into a preamp? I have a 300B SET amp and want to do the same thing.

Thanks.

To Almarg...Yes I used an old Carver wide band coupler which has prebuilt transformer and resistor step down from high gain to low gain for interconnects. I dont beleive you can find one as nice as this one prebuilt. I bought this one in the early 80,s. If you are like me you are a DIY,er and using Ohm,s Law.

However to be clear I am sure there is a simple way to use a SET for a preamp. The whole original reason for this was I realized that most RCA interconnects used about as much power as my 5 watt 6b4g tube put out. So I am going to try straight wiring my RCA interconnects directly to the neg and pos terminals using the RCA shielding as the neg and the center as the pos. The low power SET amp may not like this due to impedence but there are ways around that as per my last message. I will add a resistor(8 ohm)or(4 ohm) in parrallel and in series to lower voltage and amperage or just one way. This is the easy way to attempt this feat. I am using the volume control on my SET amp as the volume for my stereo now but I could put it after my preamp and still use the SS preamp as volume control.
