Re: Funny Story About Tweed!

Hi, for NFB on 5e3, just look at 6g2 princeton schematic. You need to remove one cap and add one 56k resistor. I did it on mine and love the tone ! Try it !

Re: Blowing fuse and hum from an effect loop

If i put one of the red arrow to ground, hum disappear. No effect when i do the same on blue arrows, even if i put the 3 arrows in the same time to ground.

Re: Blowing fuse and hum from an effect loop

I tried several other tubes with no result. I'm gonna consider elevating the heater supply 50-70V.

Thx.

Re: Blowing fuse and hum from an effect loop

Hi, I don't know why, but fuse blow again if i don't wait 30s between stand by off and power off. Ceriatone put 3A fuse on the primary of their 100W Marshall. I do it and it seems ok now. On the other side, i have hum. [IMG:200:162]http://www.image-share.com/upload/2960/107m.jpg[/img] I got 0.1V pic...

Re: Multitape OT

So, i use 820 and the 2 ohms tap for the NFB and the 8 ohms tap for the speakers ?

If I use 1k5 (2*820) and use the 8 ohms tape for NFB and speaker, it will be the same, no ? Deluxe reverb use 820/47 with 8 ohms tap. Same ratio !

The 2 speakers see half of the power each and are 35 W speakers.

Multitape OT

Hi,

I bought a Weber Multitap OT for my handmade AB763 amp. I load it with a 8 ohms cab (2x10" Jensen C10Q 16 ohms in //). Super Reverb schematic use 820/100 NFB resistors with a 2 ohms OT. Can i use 8 ohms tap for speakers and 2 ohms tap for NFB please ?

Thank you.
