thanks for following up! I'm sure somebody else will find this very very useful at some point

I don't know if attachment upload is currently working, but you can always upload the picture to an...

a nasty drop could definitely damage the tubes enough to cause excessive current draw and thus a blown fuse. after checking the basics (cables good, speakers good, impedance switch set correctly,...

it would be a disservice to the amp to replace it with anything but an OEM xformer. they're custom spec'd by fryette. I know fryette's support can be slow/hard to get a hold of, but contacting them...

I hated the wb in v1.

actually I recently posted some info about tubes in my fifty/cl in the thread called: VHT/Fryette CL100 tube question

when fryette says chinese they mean shuguang 12ax7-a....

new sensor mullard el34s

I actually recently went through a whole thing with trying a bunch of tubes in various positions for my fifty/cl. what I ended up with was chinese shuguang 12ax7a's for...

welcome. the bbcode functions on the board are currently broked for some reason so I'm just pasting your questions and my answers below them.

Q: Could any serious damage have been done from...

"G-50-CL" is the model number, with "Pittbull Fifty/CL" being the model name. They refer to the same amp.

I'm assuming the grille you're talking about is the one that looks like the current...

what happens when you use the ps-2 as a straight power amp? (plug something in to the line in, nothing plugged into the amp in)

I've never seen a diagram of the Sig:X circuit, but I believe the Sig:X is supposed to be more akin to the Deliverance, but with more switches and options, etc. The Deliverance circuit diagram can be...

this is an unofficial forum so fryette the company doesn't have anything to do with how it's run.

I've already tried reaching out to the admin about the spam issues but I've not heard back

I recommend you call or email Fryette support: support@fryette.com, they're probably the only ones qualified to make a judgment regarding the capabilities of a certain serial number.

My stereo setup! D60, D412 on one side and Fifty/CL, FB412-F70G (Fane!) on the other. Shallow stereo chorus pedal to bring it all together. Sounds absolutely monstrous and will destroy unprotected...

that FX loop is pretty tempting... but then I remember I can just play my Pittbull if I need all the fancy stuff. there's something kind of magical about having an amp that's the bare minimum while...

there is a bias trimpot inside, and moreover there is a current resistor in series with the cathodes and some silkscreened text telling you what the target voltage should be.

sovtek tubes are no longer in manufacture, unfortunately.

EH KT88s are alright but the two pairs I tried seemed to be short lived. could be bad luck.

my favorite so far have been gold lion...

I really don't think it sounds like it would be the problem, but did you swap the rectifier tube when you were retubing? I know my 50CL did some weird things when the rectifier tube was going out...

You try changing the 40W/100W power switch on the affected channels? Any change?

just to clarify, it won't make the noise, even if you tap the headshell, when the mv is turned down? if so, that would indeed eliminate the power tubes as a culprit. it could still be the preamp...

try hitting the preamp tubes lightly with a pencil or something and see if they're microphonic. v1 will be shielded so you'll have to pop that off first. it could also be the power tubes, too.

Those will work fine for V1, V2, V3. Most any 12AX7 will work fine for those positions, the ones listed are suggestions for the intended sound of the amp. Personally, I prefer a Tung-Sol in V1 due to...

When I bought my used D412 (P50e) several years ago, I assumed it was already done breaking in. Mistake! It wasn't until the past year when I started having band practice weekly at deafening volume...

Fryette sold (probably still sells) badges to retrofit on older amps. Does the silk screen on the back panel say "VHT" or "Fryette"?

from what I've gathered the first two numbers should be the year. so that would mean your amp was built in 2002

The new website is kind of weird IMO. I think it only lists amps that are currently available for immediate order from Fryette. I'd bet at some point, the Deliverance II will adorn the site again....

Regarding the signal level between the preamp and power amp, there are really only three factors that you have to watch out for: noise, saturating the front-end of the power amp, and overloading the...
