Hello everyone, I'm new here and have really enjoyed the forum a lot. Anyway, I posted a schematic of the daughter board on another thread. It's not verified yet. Here's the link:

http://www.diystompboxes.com/smfforum/index.php?topic=60386.0

I know this is an old thread, but wanted to keep the info together if possible. I see no need to chase info through several threads. I like to keep it simple. I'll post in the thread linked above or here, whichever everyone thinks is more appropriate (or start another thread if that's what everyone wants).

Does playon still have the broken lovetone flanger?

Anyway, hope this takes off!

I've been trying on different forums to get some interest on tracing this pedal. I post what I can and wait to see
if there is any response. Been slow so far, but Lacesensor has graciously stepped up and given some assistance.
I have also sent an email to a member called playon who used to be on another forum to see if they are willing to
help out. He had written that he had a Lovetone Flanger that was broken and was waiting to see if anyone could
make a schem of the board. His posts were back around 2007 and therefore he may not still own the pedal. If
he contacts me, we'll see what we can work out. It would be better to have an actual pedal in front of me, but
that's another story. I am sure there are plenty of generous members who will chime in onthis project.

Regarding the daughter board, I have found a small error. R10 should be 330R, not 300R. Will correct soon as I get
a chance and repost the schem. Also, the Brown, Red, and Blue wires have been confirmed that they do go where
I suspected they went. Pretty good guess! I have a component layout that is hand drawn on an overhead transparancy
and will soon attempt to start a schem for the main board. If successful, I will need help verifying and getting component
values for components that are standing upright.

It has been confirmed that the main board IC is a TL074.

Need confirmation on the following if someone wants to volunteer!

There are 17 transistors on the main board. Lacesensor has been kind enough to give me the following info:

11 - BC549C

2 - BC307B

4 - J113

Version 1:

BC549C - Q3, Q4, Q5, Q7, Q8, Q9, Q10, Q12, Q15, Q16, Q17

BC307B - Q2, Q14

J113 - Q1, Q6, Q11, Q13

Version 2:

BC549 - Q1, Q2, Q4, Q6, Q8, Q9, Q11, Q12, Q13, Q16, Q17

BC307B - Q14, Q???

J113 - Q3, Q5, Q7, Q10, Q15 ??? One of these is not correct, don't know which one.

He didn't give me the locations. These locations were taken from DIYstompboxes ("A Gift" thread) for version 1.

Version 2 is a more educated guess based off the "A Gift" thread (the OP used two numbering schemes in the layout).
I went with the layout that matches the actual layout of the transistors based off a clear shot of the board I have seen.

The only transistor I feel confident about is Q14 as the board is clearly marked "BC307B". The rest is a guess. Anyone
care to clarify this info???

I am also making a hand drawn overhead transparancy of the wires and color that connect to the mail board. Will
post more when I have it. If I get permission from the photo owner, I'll post clearer pix of the boards.

See this thread for schem of daughter board.

Thanks for any help you can give!

Since there appears to be no interest here, I will continue my efforts on the following forums just in case someone here is interested later.

http://www.madbeanpedals.com/forum/index.php?topic=5387.msg61770#msg61770

http://freestomp boxes.org/viewtopic.php?f=7&t=362&p=210463#p210463  (remove the space in this link)

Also, here is a link to a folder I am maintaining:

https://www.dropbox.com/sh/3v4twi2sbs0l5p7/1Ep9NbRE2T

As an update, R10 is incorrect on the schem I posted. R10 is 330R. Also, the brown, red and blue wires have been confirmed that they
connect where I thought they did. So the wiring is correct for the daughter board. The red wire may also be an orange wire on some
units.

I would like to thank Lacesensor and playon for contributing to this effort.

Jim
