there around 200watts each

Dave,

Isn't it closer to 30W?

the plate on each tube is 750volt 2 tubes per amp. i worked it out before came out to 150 watt to 200 watt. in push pull one thing it does have is a lot of power

750V EKKK.. I'm going to go buy rubber gloves REALLY thick ones

What parts were replaced in this amp ? I'm now excited to work on my first real tube amp..

 

[karma]

than i run into somthing like this. that i could have made.
o well


sold

ya just dont do what i did service the unit without dishcharging
the main cap. i did and i saw god for a second

the two blue 400watt caps on the preamp where replaced
you sure you dont want to start with somthing smaller?

Do you have a schematic or a link to one that i can look at ? Ill buy some rubber gloves. 5$ gloves = price less life maybe some alligator leads with some bleeder resistors built into them for discharging the cap's

 

[karma]

bleeder resistors is a good idea. not sure of a schematic i stopped
looking for one after i grazed the cap

i have better luck with the bogen db20s

 

[karma]

heh not sure why i used the smiley face, it really hurt

[karma]

With a Max plate of 600 V that is a bit hot... be a good idea to burn quite a few volts and bias it into Class A to get the best sonics.

dave

 

[karma]

yes there running hot biasing the tubes would be a good idea.

[jleaman]

Can i convert this tube amp to balanced inputs using a 6DJ8 Tube ?

Any tube schematics i can start staring at and learning.

 

[karma]

i have no schematic for the bogen ch60's . i was just going to part them out and make a nice se amp. but if you want to keep them together thats cool. if i had the time i would go over them and see what you could do with them but this is a bussy time of the year for me. i do a lot of renovations for the company i work for, trust me when you see them u will have all kinds of ideas


i just added a cam and wall for my office. i have over 90 rooms to drywall and paint but the moneys good

and yes its blue board but thats all i had, stuffs junk

i will go over the amps before i send them out just to be sure there working right.


cheers

I'm just asking for a schematic to work off of when i get them to re-build them / clean them up. Im lokoing to add balanced to this amp also but to keep rca in too.

Jase.


P.s I used to drywall / paint for 4 year's it a fun job.. beats talking to customers on the phone that swear / yell at you.

Maybe Planet 10 has some schematics I think he suggested a CSS circuit too.
