I was always of the opinion "if it ain't Broke don't fix it. My sonar 2340's (3) were sitting for almost 30 years. I hooked one up and began using it. It's the only one out of the three I own that is 100% stock. It transmitted fine and I thought the recive sounded fine. I finally found one of the other 2 that have the audio clipper board bypassed and couldn't wait to use it. I plugged it in and emedietly noticed the pll out of lock decimal. No receive or transmittt. I found s gentleman through a friend. This guy repairs old tube radio's. I sent it to him for the alignment. He also replaced the old axial type capacitors with new one. He left the old ones in and wired the new one's under the old stranger value one's. He re attached the tvi trap (first owner bypassed) added three new tubes four new feet and cleaned it up. $211 later and wow! The differance between the one with the original caps sounds awful. It accually transmittt ok but the receive compaired to the recapped on is not even in the ball park. If I didn't need the alignment i would've never known any better. I will be sending him one radio at a time for recap and what even else needs to be done. He got the radio on Friday finished it Saturday and 4 days later it's back and on the air. It screams and the receive is the way I recall it to be 30+ years ago. Awesome! I will be recapping my madison. I didn't think it needed to be recapped but im sure it will perform much better than it does and it works well already. Im sure the difference will be noticeable . This gentleman works on amps all kinds many nos Palomar parts. Also work on all . Transistorized rigs ham and cb. I was so impressed with his work and knowledge. He also restores old s/w radios. I will post his contract info soon. If anyone wants his information before I post it pm me and I'll give it to you. Trams sonar Browning Lafayette president uniden yaesu ect ect ect. I've been looking for an old trimmer tec for the longest time. Thanks baldpa.
