=P

I forgot, thank you very much for your useful info, i should have ask before piercing the amp lol
At least the job is clean...

Damn, i have already make hole on the side of my TT 
I was wanting a fx loop for acceptable echo/delay/reverb...
Look like a carbon copy will be for sale pretty soon...

Okay, i will try to take a voltage there while playing(i will open a jack and put aligator clip there)
Wouldnt a buffer at this place the best solution?

The carbon copy have taking it so far, i won't test too much before next step, i don't want to broke it. Still, the sound is very different in this effect loop than in front of the amp.

Okay, here it is:

okay thank you, i will read it tomorrow, i am totally wasted tonight 

Hi, i have done a mod on my Orange Tiny Terror, i have found the point between preamp and power amp, did the effect loop mod. Still i have that tone sucking problem when i use my MXR carbon copy. The effect is good, very good compared at when it sit in front of the amp but the tone is dull and overall volume is reduced.

So i have done a lot of research and so far, it seem i need a buffer. I want to add it inside the amp. Very simple on/off buffer. Don't want it to blend or anything.
It is very a impedance issue. The amp give an impedance of 100K and the pedal is not taking it. When the pedal is in bypass, it is perfect.
That plan here seem what i am looking for. But what is the buffer we should use?

thank you, i have done a first draw of the schematic, it is a lot of work.
I will look it back tomorrow to see if it is accurate, now i am at the beer state for the night...

I have found one on a site name "vibroworld" do someone know it?

https://www.vibroworld.com/parts/tech15.html#cans
at 60% of the page, it is labelled " 40/40/30/20 ", sorry, i can't do a direct link...

Or there is this one that is close, i don't know if it is acceptable:

what do you guys think?

It is writen:

I will do the shematic before, that is a good idea. I will have time anyway before i have all the part and the new enclosure done.

The power tube are two 6V6
the preamp is a 12ax7 and a 12au7

is there another name for multi element capacitor? I don't find them on digikey..

Yes i was talking about stand by, thank you.

So the only dangerous cap that have to be discharged is the multi-element cap?

Thank you for the advice, i will take great care with them. I have buy a book on tube amp on amazon, it is called
"the guitar amp handbook" by Dave Hunter.

That will be a long term project anyway, like 2 or 3 month, i am preparing myself to enter at university in civil engineering, so study and work take a lot of my time. But i can't help it, i like electronic project


@Bill Moore: yes i have listed every resistor and cap, so if anything burn, i will be able to know the value..

No i don't have any experience with tube amp exept for owning many, but i never service them. I have build several chipamp, active crossover and electronic volume. I know about the lethal voltage, i will identifie where the hi voltage pin are on the tube socket and follow the path. But an accident can happen so fast... Is there a way to draw the current stock in the cap?

I also haven't work with multi-element caps, i would not mind to have something that do the same job, even if it don't look the same. I consider to make an enclosure out of copper, with a mirror finish.

I don't know the history for the fuse, but i agree with you!

I have another question, that amp don't have any bypass. So i will add one. There is two way that i can see this work, i don't know witch is good: the switch can turn off the signal path or it could turn on the heater. Witch one is the good way?

Thank you for your help!

Hi guys! I am new to this forum, i have done several project for audio, but more in hifi. I am a guitarist for about 14 years. I have found in a basement a old forgotten amp by an old tenant. I have identify the combo witch i remove the head. It seem to be a Gar Gillies amp. I have try it, it sound sooo good.... and soooo loud! too loud to be honnest... Anyway, the tube still work but they are in bad shape and of course, the pot make a lot of pop.

My question is: the electronic inside is old, is there part that have improved and would be a good idea to change, like cap? I will change the pots and tube, probably add a gain channel by building a "real mc tube" drive that could be switched. A new enclosure too... Your input are welcome, here is some pic of the beast:
