Yeah. That's from the helicopter. Lol.

No. This amp is totally analogue. Lol. It's got the older components in it. Barrel resistors, 8 pin op amps, etc.  :-)

I'll be putting those pictures on here maybe tomorrow. If not tomorrow I'll get them up Monday. I have a gig this weekend.

Oh Lord. I just replaced all of those. Lol.

The more I think about it, the more I'm wondering if it blew the fuse because of the possible wrong resistor value since its one of the first things the power sees after the bridge rectifier and the filter capacitors.

Yeah. I think it was the left over clippings off of the capacitors I put on there. Maybe the rectifiers. Lol.

The clipping diodes I was talking about was on the preamp board. I'll show where they were as best I can.

Awesome. I was wondering how I could do a controlled supply voltage to test with. I don't have the bench equipment to do that so this is really a good way of doing it. I'll have to post pictures of the amp's innards. I did have a couple problems on one of the rectifier circuit board traces. I thought it was desoldered and loose from the circuit board and it wasn't and the trace lifted off the board.  (double sided circuit board)  :-(    I fixed it the best I could with solder lead clippings. I know this throws a bad part in it but as far as I know, it's connected as it should be. Pics later. I'm also sorry I'm not on here more. I get distracted by life. Lol.

I have pictures of the Classic but Idk how to attach them on here.

It also uses a different footswitch. The Randall RG100 ES uses a rectangular plug for the footswitch the classic uses 2 mono 1/4 inch plugs.

I think the Randall RG 100 Classic predated the ES.

It was made when the original owner of Randall Amps made them. It's blowing fuses which tells me there's a short in it. One of the resistors was slightly discolored in the power supply and I'm not sure if I replaced it with the right one. I measured it with a multimeter and it read 300 ohms but I think it was weak and slightly toasted. So it's not gonna read right. At first the amp would come on and then blow the fuse, now it blew it once and it don't come on at all. I think the original problem was somebody attached a couple of diodes onto the clipping diodes and it was causing a short. I removed them then I replaced the output transistors, regulator, rectifiers, and the filter capacitors. And that resistor. But Idk if I replaced the resistor with the right one. The reason I thought about replacing it with the ES power supply is the schematic is available. I just don't know if the specs are the same.

Hey there. I'm new to this so I'm going to try to be brief in my description of my problem. I have looked high and low, near and far for a schematic for the Randall RG100 Classic. I'm a novice at discerning the layout of an amplifier. I know how to read a schematic and I know how to navigate through it enough to know what parts are used. My only source for any kind of schematic for this amp is that of an RG100ES. There's differences but I can't tell what all the differences are as I haven't went through it with a fine toothed comb. I know the output transistors are difference but they seem to run off the same dc voltage. Beyond that I have no clue what's the same/different. I need the right schematic. Can anybody help me? I had also thought about converting it to the ES power supply if that would work. Any thoughts on that, too? Thanks in advance for any help.
