Old 36 watt build - a little help tweaking Please!
Posted: Fri 01/02/15 11:28 am
So I built this 35 watt back in '06........
My son has had it, yet he says he rarely uses it for various reasons (he is a giggin musician).
By and large he says 3 things:
1. It is too LOUD! I decided what he is saying is that in club gigs, the Master Volume is so touchy under a 1/4 it is too difficult to get the volume right. He's right, it is!
2. The Bass pot doesn't seem to do ANYTHING?
3. The half power switch (grounding out 2 grids) when engaged takes the volume WAY down and there is little actual volume control?
So I am thinking out loud here....
1. Change the 1 meg Master pot AND the Bass pot to 250's. Or at least on the Bass, raise the value of one of the cathode bypass caps way up to get more bass overall.
The half power thing I don't understand? Thinking of changing it over to ground out the cathodes?
Comments? Suggestions?
