Title: B&W 2500 Keying Problem Post by: KD6VXI on December 23, 2018, 07:52:00 PM Bob,
Saw your post in the for sale section. Check q1 through q3 and the associated capacitors around that circuit. I'd also wonder, is it pulling zsac when keyed, and no rf getting thru.... Or more like ground the ptt and it acts like nothing happened. I own one..... Great battleship looking amps. Have bugs, work them out and they work well. But, not kne schematic will match what is in front of you..... I got lucky and mine came with a hand drawn schematic from Viewstar that matched what the amp was.... --Shane KD6VXI Title: Re: B&W 2500 Keying Problem Post by: K9EID on December 24, 2018, 07:54:24 PM Thank you Shane. I appreciate that. Will get into the situation in a few months. Want to bring it back to it's total life and of course, do it right. May have to call upon you for your schematic.
Appreciate your time Bob Heil, K9EID Title: Re: B&W 2500 Keying Problem Post by: KD6VXI on December 25, 2018, 12:49:57 AM Not a problem.
//Supposedly// mine is the one they fixed a bunch of problems with. //Supposedly// that means it's the one KM1H did some work on. The serial number does fit the timeframe, so who knows. Anything I can help with, other than Millen connectors, please let me know 🤔😁 --Shane KD6VXI Title: Re: B&W 2500 Keying Problem Post by: K9EID on January 07, 2019, 12:04:00 PM Shane
Possible for you to send me a copy of your schematic? Like to have a perfect schematic before jumping in. I thank you Bob Heil Heil Sound 5800 North Illinois St Fairview Heights, iL. 62208 K9EID@arrl.net Title: Re: B&W 2500 Keying Problem Post by: KD6VXI on January 07, 2019, 02:25:14 PM Bob,
I'll scan and send tonight. If I forget, please remind me. After blasting myself with 6kv three weeks ago, the mind is semi forgetful. --Shane KD6VXI Title: Re: B&W 2500 Keying Problem Post by: KD6VXI on January 08, 2019, 10:13:59 PM Bob,
I haven't forgotten. Have put in 14 hr plus days last two days at work. Will be scanning and sending soon! --Shane KD6VXI Title: Re: B&W 2500 Keying Problem Post by: K9EID on January 14, 2019, 10:25:06 PM Hi Shane AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
looking like I have found some time to get with a friend who has decent workbench and is willing to take on the 2500 project. If. you have the schematic, I will appreciate that very much. Best to send it to: K9EID@arrl.net Really appreciate that. I finally got the microphone connector situation all worked out - built it using one of our 'stealth' shells. Works great and the little MARS is on the air. so much fun. Really appreciate your help. Bob Heil, K9EID |
