hello, I am wanting to replace a 2n5088 with a can style tranny - can someone help me with a data sheet; such as what to look for and why when substituting.

This is the LPB1 which I have been working on. I breadboarded it, learned how to follow the flow on it ..now its time to make a tube amp style layout!  I need to learn what to look for in substitutions like the transistor. I know you can swap stuff in and out but I want to know what to look for on a data sheet , if you know what I mean ..

also, this is just a mechanical connection - the clean side sounds freaking awesome, but when I go to my dirty channel a loud hiss, squeal and hum occurs , like a sustained squeal , truen on clean and the pedal circuit works exactly as it should ..its really boosts the signal  I bet up to 3x or more.

A BC109C will get you in the ballpark...and it's available in a metal can.

I just designed a new fuzz circuit! It almost sounds a little different than the last fifty fuzz circuits I designed! ;)

Thanks Larry ! appreciate ya. I am guessing, since the Hfe  lower and upper limits are 100-800 I can use it?  I have some that read beta 450-520 and I have some npn germaniums that read beta 650+

I guess i need watch a youtube video of what the beat and leakage mean lol

The test conditions are not the same between the 5088 and BC109 data sheets.

I suggested the 109 because it shadows two of the 5088s known parameters. High gain and low noise.
They are not an exact match but...you may not be able to tell the difference.

Leakage does not apply to silicon transistors. Both the 5088 and 109 are silicon.

Use the search function above. You will find volumes written by very knowledgeable individuals on the subject of transistors.
