Have a very good condition Thunderbolt 305 that has been converted from 6LQ6 to 24LQ6. It's one driving three. I saw it doing 600 PEP watts on a Paradynamic PEP meter. My Daiwa CN-501H does not have true PEP, but does have an average and PEP switch. On the PEP measurement setting, the Thunderbolt does just a tick over 400.
Now to the problem I am having. I can do line recordings from my RCI-2980 20 watt radio to my computer. While using stock dynamic microphones with the amp on, the transmitted sounds like there is a blanket over the mic. Amp off it's crystal clear.
Using an amplified Astatic mic with amp on, the transmitted sound does not sound like a blanket is covering the mic. It does lower the tone on the mic transmit sound just a tad, but it still sounds good.
I have tried three different stock microphones including Ranger SRA-158, Stryker stock mic, and a SuperStar. All of them sound good with the amp off. Turn the amp on, and they sound like they are covered with a blanket...slightly muffled. Have verified this problem over the air while talking to a friend.
I have lowered dead key on my RCI-2980 all the way to one watt, and it's still the same. Amp on carrier watts of 70 to 125 does not change a thing with the stock mics.
