front baffle no fiberglass. I got my speaker from some local garage band.
I remove all the fiberglass try to patch up some holes and properly not going to put the fiberglass back in. For damping material I’ll probably use Cellulose Wadding.
I been playing with the darling amp for 2 weeks now But I still cannot figure out the problem I have from the start.
On the schematics between the rectifier and the choke 1.5K resistor 5 watt, I have to used 500 ohm 50Watt to get my
B+ 259 DC
1626 plate 242 DC. Heater 12.8...
I noticed that Metal tube is more Noisy Then Glass tube On my amp.
I add two 100 ohm resistor to heater to ground That help lower the hum a lot.
I still hear little hum if I put my ear 4 inch to the speaker.
Hope that helps
my B+ Is 182 vdc not 380 vdc
using blue wire 121V primar tap
I think my B+ is low Because of the choke I used
My B+ to 1626 plate was 182 vdc if i use 1.5k resistor before the choke, I try with Couple different resistor and 400 ohm will give me 250 vdc
(waiting for a 400 ohm resistor)
Hello everyone happy Father’s Day
My setup now is not using the 3000G Tweeter.
If I plan to use 3000G As a Super tweeter in JEL Universal Altec 2-way XO with HF EQ circuit
Could I follow this schematics from JE Labs?
Adding 16 ohm L-pad and .7uf cap to JEL Universal Altec 2-way XO with HF...
