If the speaker is 4 ohms @25 watts you would use 5.7v for 1/3 power.

IMO this is a good way to go because it is a very simple approach.

1/3 power is in no way ambiguous but you do have to calculate it correctly. You can’t calculate the voltage without using the resistance. This is clearly stated in the links you…[Read more]

The C10r was subjected to 8 -10 hours of 60 hz at about 1/3 power (8.1v) and the output at that point had increased by something like 8db measured at the face of the speaker. This was done with the bare speaker sitting cone up on my bench.

I did not start with a virgin speaker as it already had a few hours on it and I had…[Read more]

I will try that while running on a 60hz signal.

I tried lacquer thinner also and that may be a little more effective than the acetone.

I don’t see how you can fry a speaker at 1/3 power.

Are you suggesting the 1/3 power 60hz method? Somehow I got the idea that it took hours of that to break in a speaker.

While we are on the subject any experience with removing or reducing the doping on the surround?

Thanks for the response. I have no problem understanding what you are saying or the info in the links.

I also realize that if I use a 6k6 that I am running it beyond its rated plate voltage. That said part of the rational of this design is that it is suited to various output tubes per Dave Hunter. I have not calculated load lines for the…[Read more]

Perhaps a little clarification of the question is appropriate at this time. I am not expecting I will necessarily like what someone else likes or that my amp / speaker / guitar combinations will sound exactly the same.

The 6l6 is an old GE and sounds very good. I tied pin 1 to pin 8 as it would be in most beam tetrodes. I guess it is not much difference connecting it to ground. Just a little longer wire. Perhaps I will try that. Seems a pretty clean solution.

I floated all the jacks and only tied the ground bus to the chassis at one location. I neglected to tie the bottom of the output transformer back to the ground bus.

It is now dead silent.
