36 watt TMB

[Calamardo]

Me again!!!!, i have some obsession for 36 watt amps but i dont know very much about make amps without a good schematic and layout. I want to make a good 36 watt and i saw that RICHIE built a 36 watt TMB. It´s available a schem, trannys spec, etc?.Thanks

It progressing..i have the trannys,and Nik is doing the boards and chassis,faceplates.. He has the first chassis done.Nik will also have the layout. So when i get all the parts here,i'll try to take pictures as i build the amp.it may help others. If there are no problems,then Nik will have
the chassis and boards for the amp. Now if your doing one of your own,like punching your own chassis etc.. we don't have the layout posted yet..

ok thank Plexi. Is possible change the valve rectifer to 4 1n4007 diodes? (the ez81 is expensive in my country).If is possible i need the b+ voltage to calculate the power tranny, you understand me?

[Plexi]

The 36 watter uses a GZ34/5AR4 you could use an SS recto..
The tranny i used has a 5V tap for the recto..but here are the specs,So you can use either SS or recto tube..

120 v pri . 280-0-280 @ 200mA 5v @ 3A and 6.3 @ 6A.

Since i'm not useing a SS recto i had this tranny bumped up to 290-0-290

thank you Richie!

Richie, can you tell me the b+ voltage value, before the two 32uF caps ?. It help me to order the power tranny. I think is about b+= 280*1,4=392v for SS recto (1n4007). Thanks
