Re: PT voltage question
Hello btw. (or something similar)! But with so many volts it's understandable, that you forgot to mention...

Removing some windings from the HT secondary or another PT - anything else is a crutch and should be avoided.king9968 wrote:... what do i need to do to bring the voltage down to the 325 range

The fault almost always is sitting in front of the amp

Re: PT voltage question
interesting most likely true. Im just trying to make a amp from what I have stockpiled . My grandfather witch was a tv repaire man back when people use to fix their stuff he passed away and I got all his electrical treasures one tube contraption from 1/16/43 looks like something from an old tv huge tubes bigger then 6550s anyway I got lots of stuff to play with. I've built a 18watt tmb from a layout.I have not found anything I would not try to fix or make, But still learning everyday.

Re: PT voltage question
Are the pop rivets aluminum?
If they are solder won't adhere to them.

Re: PT voltage question
I build with "other iron" frequently----the Mule M50 head in the amp clips (see my signature) has a Dagnall OT from a 1987xl that i got off the 'bay when somebody "upgraded"---the cast-off OT works pretty well.king9968 wrote:Wow I cant believe that im the only person in the world that wants to build with somthing that did not come from a kit.btw I made my turret board today out of an old clip board and some 5/32 1/2 inch pop rivets.
I just ordered some Edcor PT's for 50 watt builds: http://www.edcorusa.com/Products/ShowPr ... spx?ID=677 --- i haven't used this PT before but i've used other Edcor iron-----i'll post when i build with one of these----- i'll be using some CE Dist 50 watter OT's i just got or i have some Merc Mag OT's on hand----thinking of a more modern sounding build........................gldtp99
PS-- It's true---- aluminum and solder aren't a great combination
