I need to work on the amplifier board in a Proton 300 radio.
The woofer has no sound at all, but the tweeter seems normal.
The Proton's service manual is pretty bad. Can anyone explain
the correct way to remove the back of the radio (which has
the amplifier board mounted on it)? Thanks.

Before looking into the amp board make sure to check both the woofer and its connection.

How do you remove the rear panel?
The manual says to remove the 4 small screws,
but it still won't budge. Are there other screws
to remove, or is it just a tight fit?
Thanks.
I couldn't download the service manual. Sorry.

Here's the Box link to the Proton 300 service manual. Thanks.

Based on the one diagram and not seeing the unit on person I'd try going in from the front.

Ok, do you think the woofer can be removed by removing the 4 screws
holding it to the front? Are there nuts on the back side of the
woofer screws? Thanks.
Yes I think it comes out the front too. I doubt there are nuts on the backside. It also looks like you remove the square panel on which the speaker is mounted.

If you're still having trouble, it seems to me that you might have to remove the tuner section first. Then you have access to the rest of the panels.
Ok, I'll give it a shot. Thanks very much for the advice.

I placed a copy of the service manual in my Box account.
Can you send me your email address, and I'll send you a public link?
Or I can email the file directly to any email address. Thanks.
