Rerurn to Romy the Cat's Site

Hi Romy

I have one gas tube which regulates at 136v and i put it in both sockets to see the effect. Looks like my tubes running at higher voltages gives me the readings I got. Anyway I bought a bunch of gas tubes and will play with them when I get them and am not too concerned and am quite happy with with the voltages I get..

Also i stick a 30k resistor in R3 and the results are very good. The voltage measured at the speaker terminals are 0.3mV AC with the iput unshorted. Also this stabilises some voltage dc drift in the input. The amp is very quiet. Now I will finish off the other onoblok and see how they sound.

i use the lundahl LL1627 amorphous core opt 200mA. maybe later on if I decide to go for a bass amp I will try one from a local  winder with high inductance. i use some home built horns front loaded round tractrix, 3 way. 1/4WL 120hz full size mouth midbass horn, 400hz tractrix and sealed woofers.

i will post some pics soon.
