Help in building a PT-80

[johnyze]

Hey everyone, how's it going? I'm working on building a PT-80 delay pedal off www.ustomp.com because that is the board etch I have. However, the page is sorely lacking in explanation, and I'm having difficulty figuring out what some of the parts are. For example, what is Q1 and Q2 mean? I'm sure these are abbreviations for something, and I'll probably feel very dumb when someone informs of their meaning, but I can't remember. Anyway, any help with this would be so much appeciated. Thanks everyone!

Components labeled Q are usually the transistors in the circuit. Q1 and Q2 are probably the 2N5088 and the FET for the indicator LED.

I modified the schematic a little.

If I remember correctly I took out the 12V regulator as I run it off of the 12V supply from a voodoo labs pedal power. I also took out the LED switching since I am using a 3PDT not a 2PDT switch. I also added a Pull down resistor to stop the clicks w/ the 3PDT.

Components are as follows:
Q1 2N5088
Q2 78L05

BTW, you can also run it at 9V. I do and prefer it that way.
