TSE redone..working well..but :)

Green77 · 28th June 2011, 04:05 AM

Hi all

I just redone my TSE and it works very well.

Anyone used a delay for the speaker output?
My TSE makes a "BHUUUUUU" sound when the heater is staring up.. for about 15 sec.. i use SS and not tube for the B+..maybe that's why..

thanks // Daniel

Most likely. The tube rectifier for B+ allows all other tubes time to warm up before the plate voltage is applied due to slow start of 5AR4. It's said to be good for other tube's life expectancy. By how much? I'm not sure.

Installing delay for speaker output won't help saving those tubes though.

Are you running 45s or 300Bs? The hum may be from the heater regulator dropping out of regulation while the filaments are coming up to temp.

300b..ok i can messure the 5v volt in the weekend

Do you have a scope? If so, put the probe on the heater supply and see if the ripple comes from there.

my friend have a scope but he's gone for 5 weeks

Don't know if it's sounding like ripple..more like a ground sound..hard to describe

Well, it's going to be more like a buzz at 120Hz.
