The missing ball...

I know. Sounds like a personal problem...

Where can I find a pair of "Johnny Balls"? I have a tower that somehow is missing one...

Re: Audio Limiters Volumax

LOL.....

He's right! ut, a Volumax 400 will be just fine.

I'd love to find a Levil Devil for less than a king's ransom. Sadly, we were too anxious to throw out all that old tube gear...

Re: Autogram dual input card

He seems to think those chips aren't the issue. I checked availability and China or Hong Kong seem to be the closest place. I'm going to try a couple of other chips, but with what seems to be obviously a "wide open" failure, it is hard to imagine anything else being the issue. Luckily I had spare in...

Re: Autogram dual input card

I did hear from him, and he sent me service info. Unfortunately, the chip he said was most likely to cause the problem (and the one I had a spare of) didn't fix it. I don't have any SSM2018T chips to try plan B. Time to cobble up an order to the IC store!

Re: Autogram dual input card

I have that manual. Unfortunately, the card in question is apparently a 2004 upgrade, not to be confused with the card in the manual. Anyone have a spare older card? I could also use an A-B input switch.

Autogram dual input card

I have an Autogram Pacemaker 1032 with a bad dual-input card. This is a newer (2004) version of the card with dip switches on the top edge. The VCA is bad as there is no control over levels. Maxed out all the time. I don't have a print of the circuit and I haven't been able to identify which chip is...

Re: Xmtr output bouncing

I have mine behaving itself for the time being, with auto power off. I really need to take it off line and give it a thorough inspection. It does have two new tubes in it and the readings are where they should be. And that's a good thing!

Re: Xmtr output bouncing

Thanks for the input. This is WLTU's box. I did not know that tidbit about the raise/lower lights, but it makes sense. I come out here twice a week. Put the power control switch in 'manual' and it has stayed between 95-99% power, which is about the same as the auto power kept it. I'll go back and re...

Re: Xmtr output bouncing

I have an inherited CCA FM8000GZ running at 4kw with a YU148 final and a YU181 IPA. I'm having issues with the auto power and for that matter, the manual power. No matter which way I turn the power adjust control, usually both the raise and lower led's light. Once in a blue moon, one will light but ...

Re: TFT 884 Mod monitor

Some companies (e.g. Orban) put their manuals up on an ftp site. Not TFT. I finally heard back from them. They want $75 for their stinkin' manual! No thanks. I'll hope someone has info. What I need is the proper way to set the two front-panel calibration controls.
