Guys, I'm learning a lot from you guys about the "idiosyncrasies" of this rig. In a couple weeks I'll be ready. Thanks! [email protected]> wrote:

One thing that can affect how loud the radio sounds is the IF Gain adjustment on the 2nd IF/Audio board. The adjustment given in the service manual is vague. Too low and the radio will not be as loud

Hi Bob, I'm also bringing back on line a TR-7.? ?This is one that I had bought a few years back from Fair Radio during a store visit.? It was complete, but not working. My TR-7 was exhibiting the

This is starting to remind me of the old "Car Talk" radio show, when the caller would describe the sounds their car was making :-) Steve Wedge, W1ES Time flies like an arrow. Fruit flies like a

Congratulations Mark! You hung in there and found it. Great work and thanks for letting us learn though your problem solving 73 John K5MO

Both are a great idea! Gary W0DVN

Hi to All! I just acquired a T4XC that I've been going thru, with the intent of pairing it with my R4A.? I was wondering if it's advisable to install a capacitor or a couple of crossed diodes across

And it’s not a bweep sound it’s more of the sound of a mouse when it makes a tiny squeak. Mark

I am at work right now but when I come back home I will see. Mark

Also, you have not answered the question as to whether or not the loudness of the BWEEEP? sound changes when you cary the AF Gain. Gary W0DVN

If you turn the AF Gain up on a strong signal, to an annoying volume level, do you get any evidence of howling or oscillation in the audio? Gary W0DVN

I believe you’re speaking of C135 the 10uF cap on V17. Yep I replaced that last Saturday! Mark

The can capacitor is additional filtering, mostly. The other one that can be a problem is the one in the cathode circuit of the audio amp. It’s a 10 uF, 25V and is used to bring the cathode to AC

looks to me like the big can was replaced by a previous owner because it says Hayseed was n it and I already tested that cap out when I first bought it last month. Also the small electrolytic was

If you haven’t changed that can cap and nobody before you did, I would do that before even powering up again. That cap is a known problem. Steve Wedge, W1ES Time flies like an arrow. Fruit flies

That’s sort of funny to me when I think about the “Vintage” Carver Magnetic Field stereo power amplifier I have in the basement. It works perfectly, sounds great. However, when I turn it off, it

Hey Terry thanks for responding back to me. No it's definitely coming from the speaker and it makes the sound when being powered "Down" not up. Mark

Good. Study it. It is very good at telling you how stuff works. One of the best SMs I have seen. Also check the +24V for ripple. The main filter, C2108, is a known failure point from age. It is a good
