Thanks. I'll check into it.

I used the schematic from fuzzcentral. It's the arbiter version. It sounds very authentic, so I don't suspect any errors in the schematic. It's just the behavior of that fuzz control that I don't like. I've seen demos of the tonebender mkII, and the attack control on those seems to have a wider useful range.

Thank you both very much. I've tried several diodes in there, but got a distorted sound and alot of heat coming from the amp, so I had to shut off power very quickly. I became somewhat disenchanted after several attempts, and left it alone. Externally, the amp looks great other than a bit of rust on the corner caps. I wonder if someone had been driving the amp too hard over the years. Thanks again guys.

Thanks, but I like to be able to adjust the amount of fuzz to some degree. The problem is that it gets almost no fuzz until the last few degrees of rotation of the fuzz pot. When it gets there, it just sounds too muddy for my taste. I'd like to extend the useful range of the fuzz control, is all. Thanks again.

  Someone on ebay selling those 1N3754 has the spec listed as:
100 PIV, 125mA, Vf = 1.0-1.1V
Does that sound right?

Thanks, but I have no idea about any of the specs for the original part. I guess the amp may just have to sit there and look pretty for a long time. I appreciate your help, though.

That looks just like it, except for the number. I can't get those pics yet, but I will as soon as possible.  I don't really feel up to moving the amp right now. Thanks again, Juan.

Thanks,Juan. It was exactly the same size as the metal can germanium transistors. I'll try to get some pics, if I get a chance. Thanks again

Thanks, Juan. I can't get a picture of the transistor because I lost it. It had some kind of fluid leaking out of it, which I noticed once while working on the amp. Shortly after, there were intermittent popping sounds, and loss of output when the amp had been on for a certain amount of time. Then one day I turned it on and ...nothing.  The part had a clip that it sat in, and when I moved it to get the number from it, the leads broke off. I tried to keep it, but it was eventually lost. I read that this amp is supposed to be identical to the Kustom K 100 (internally) . When I get the chance, I'll try and get some pics.

Thanks.I have posted about this in another forum. Part of what you said was also written on there, but not all of it. Thank you. I'll have to try and find one of those, although it's extremely unlikely that I have one. And yes. I'm aware that it's just a rebranded kustom. That's why I wanted it in the first place. I'm a CCR fan. That being said, I constantly played through it until it died. The reverb was amazing. I never even put a grounded cord on it, either. I was going to, but couldn't find one that was long enough.

Hi, all. I have a 1973 Kasino guitar amp that needs some work. I've had it for a few years now. I got it at a pawn shop for $40. The guy couldn't tell me if it worked or not. It did (after some tinkering) for about 9 months. Then, one day it stopped. I found the problem, but haven't been able to find the part to fix it with. It was a germanium transistor with only two leads, and the number 61008 on it. Is there any way to repair this amp? Or, should I just write it off as junk? Thanks

Thanks, Juan. I can't blame you. I love my fuzzrite clone. I did try some C1815(said to be BC109 equivalent)  . They sounded awful, but they worked great in my fuzz face clone. Maybe they're not exact replacements, then. I have to use whatever I can find in scrap electronics. Old TVs, radios CB 's, and stuff like that. So, getting the "right" parts is usually very difficult. I really wanted to build a tonebender mk II, but still haven't found the parts. I always wanted a fuzzrite,  ever since I heard " In-A-Gadda-Da-Vida" when I was 12 or 13. I just loved that sound. If you say these other transistors will work, it's worth building another one someday. Thanks again.

Thank you for your kind words, Phil. I've been wanting to get some of those books. I have a very limited budget too (actually, no budget). My amp is solid state. It's a 1970 sears 125 XL. It's noisy, but I love it. I sorta came to that conclusion about frequency after looking at all those data sheets. I didn't mean to cause any trouble.  I don't like to cause trouble.  I meant to help. Oh. My guitar is a beat up epiphone Les Paul standard. It has the stock pickups. I always leave my uni vibe clone hooked up, as well. I get a nice cocked wah sound that way when I back off the guitar volume. The pedal, and my amp are all treble. There's hardly any low end. That being said, I have tried this pedal through four different amps. Including my old sears amp. I also have a peavey. The pedal did sound quite different through that one ( think maestro fuzz tone) . I've also tried it with a few different guitars. Stronger pickups tend to make it sound pretty raunchy.

Hi. I have a question regarding the fuzz face. I built the si version, and was very dissatisfied with the fuzz control, or lack there of. My question is this. Is it possible to put an extra boost stage at the front like a tonebender mk II?

I'm also planning to build the Ge version, but I don't have all of the parts yet and I have other projects going on. I'm trying to fix up a motorcycle. I'm gathering parts for three other pedals, as well. So, I'd really like to hear about your experience with an original fuzzrite.  :tu:

Thanks for being a little more reasonable about it, Juan. I didn't mean to cause any trouble. I have compared my clone to videos of original units, and it sounds very close. So, you had an original? Nice.  I looked up the data sheet to the BC147. It specified hfe of 110, and frequency at 150 MHz. Are these still available? I'd be interested in trying them. Mine already has a buzzy sound, but cleans up quite well when the guitar volume is backed off. It's very responsive. I'd like to hear more about your experience with the original. How long did it sustain? And was it noisy? I couldn't find much information about the original units. So, I'd really like to hear some details from someone who has owned one. Thanks.
