Total Novice Inquiry Into "Tin Headphone Amps" (Cmoy) - Page 3

SO if I go ahead with the 470uF 25V caps and the 0.1uF input caps, all I want to know is if I'll get good sound or not. I would prefer to head good sounding bass and vocals. My Shures already provide this but the whole reason of the project was to make them even better. 

okay. Well I ordered the wrong input caps. And I refuse to pay $20.00 shipping for 2 20 cent input caps, so i'll have to salvage them.

This is a pic of an input cap on a old component board I have. I personally think that it's a 0.47uf 63V cap. But I'm gonna need conformation that if I do a good job of desoldering it outta that board that it'll work good in my Cmoy.

Here's a pic. It's the yellow one. I think that the manufacturer is Vishay?

Thanks guys.

Oh and one more thing. How do I go about adding an additional 9V battery into the cmoy for 18V? I don't think the tangentsoft tutorial went over that.

what did you order?

 

just put another nine volt in series for the 18 volts

 

cheers

FRED

I ordered the 0.1uF. Will it still sound good with the 0.1uF though?

Lol ok Fred.

Do you mean low as in lame? Or low as in bass?

Alright. Once I pick up the final part (protoboard from R-Shack) tomorrow, I'll get busy making my awesome sounding amp! :)

It's gonna take a lot of rewatches of youtube tutorials though. And I still have yet to find a tutorial that explains how to add an additional 9V battery, which is a problem since I require more than 9-volts for my dual-opamp setup.

That makes it look a lot easier Fred, thanks!

I am also looking for not the scematic drawings but the drawing of what everything looks like on the protoboard, essentially a schematic for people who don't understand a real schematic. I believe you had one in your stripboard cmoy build thread, but I am looking for one for the common Radio-Shack protoboard usually associated with this build.

Yea, I guess that will do, but I was looking for like a hand drawn (computer program drawn) drawing.

Hello All,

Just started building today, I'm almost done, all I have left to do is finish the connecting the pot and the input and output jacks. 

I have one HUGE problem that I will need expert help with. I stupidly decided to buy the pot that served as both volume control and as a switch. Connecting it into the circuit is not documented on the internet. The pot has like 9 pins on the bottom, and I have absolutely no clue of where to solder which and what wire goes where, it basically makes no sense. Also, Tangentsoft did not outline very clearly soldering both the pot and the input and output jacks. If anyone could help me that would be very much appreciated. Here's some pics of what I've got done so far. Yea I know I suck at soldering, but as I said, I'm a noob. 

Pot and input jack.

2 9V snaps connected in 18V series. I have a bad feeling that I'm gonna need to cut in half the red wire to somehow connect it to the POT. How and where to solder it, again, I am begging for help on that topic.

Bottom of the board. There are no bridged connections. 

Please help! Thanks.
