Schematics and Layouts / Frontman 212r
« on: February 17, 2019, 12:11:35 PM »
Hello,

I'm having trouble finding the part number to Drive / More drive switch.
S1 on the schematic.

Can you tell me the correct part number to order?

I ordered the wrong one 0028091049 online, its a little too small.

Thank you for your help and advise.

Schematics and Layouts / Re: Adding Bluetooth to lm386amp

Good Question  :dbtu:
It would be pretty cool to be able to add a bluetooth module.
I see "how to" on installing something like that inside a radio.
Neat feature to play along to some music.

cool, thanks for sharing. :dbtu:

That Yamaha Amp really sounds good.  :dbtu:
My Dad asked me if I wanted to use it a little longer. I told him he better take it because all I'm dong is playing on it. I'm not getting my other stuff done.

Yamaha really made a sturdy amp. the wood in the cab was real thick and heavy!
Im curious if the Series II and III are as heavy duty.
Anyone have any idea?
What are your thoughts on Yamaha Amps? Good, Bad, just OK?

I blogged on it. Nothing more that is not posted here.

I did not see knobs like yours on their page, so I emailed them. Lets see what they say.
I attached your image to the email.

Hello,
We are looking for some Yamaha YTA-95 guitar amp knobs.
Do you have anything like that?

Take Care,

Those are cool looking.
Could you take a regular knob cut a notch and paint it? You may need to do a whole set so they look the same.
The basic shape looks like these.

OK, so TR206 and TR207 can cause that popping!
I removed them, and I cleaned the pots.
Enzo rocks! I should have just listened to him in the first place. Thanks.

I will mess around with it some more, and to make sure nothing else is wrong with it. I also need to do some very minor cosmetic stuff to it.
There is a tiny tear that I don't want to get any bigger.
and someone replaced a pot, but put one in that the shaft was too big, and just cut it off to fit. but the knob doesn't stay one. I'm going to try and cut a slit it in it since it now longer has one.

I think my Dad will be happy with it.

Picked up some thermal Paste, got the amp back together.
I bought 2 NTE458 transistors to replace the bad transistor 2SK30A (replaced the pair of them).
I did not not try the amp without the transistors like Enzo suggested. I was there getting the paste...
The amp is now loud like it should be.

BUT,
There is a very loud popping noise. Ive twisted all the pots and it doesn't seem to make a difference in the popping.
Turn the amp on with or without guitar after about 15 or 20 seconds it starts a loud sporadic popping. Turn the amp off, then back on another 15 seconds or so it starts again.

I did notice that sometimes when you turn the amp off, you can hear some static sound from the speaker for a few seconds. Im not sure if that is normal for this amp.

Would the 2 transistors I replaced (TR206 and TR207) cause that type of fault?

I have NOT done the adjustments yet that the service manual says to do. Figured I'd post here first. Then go back in and see if I can do that.

No iPod, I have a few old portable radios in the garage. I will get one.
You mentioned you plug in after the preamp. I will need help figuring out where that is.
I will take a picture of what I find.
My truck is making a popping noise in the suspension somewhere that I need to look at this morning before the heat rolls in. just waiting for some light outside.

I like the radio idea better.

I will look around for a radio, it will give me some more chances to learn something more.
Thanks Enzo!

(Put a new belt on my Weed Wacker, Nope I didn't know they had belts either. $8 and back in business)

Signal Generator
Looks like I might have another project!

Any suggestions, things to avoid in building a signal generator?
Looks like there are a lot of kits online. Some of them look pretty complicated to me.

Do I even need one to mess around working on Guitar Amps, or radios?

This stuff is better than Legos!
Cant wait until my son is old enough to get him into it.

Lets see some pictures of your set up? :dbtu:

Anyone watch Mr. Carlson's Lab? That dude has a setup.
He really looks like someone I was in the Navy with.
