Hi King,
The receive audio on the Mark IV is better than the 201A. Probably just because the speaker is larger. I get good reports from both radios. I don't think there is a big difference.
My Mark IV is all original and dead keys 4 watts and swings to about 6 watts (re-tubed and re-capped just last month). My 201A could use a re-tube and re-cap. It has also been modded for more power. Leave the noise blanker switch in, and it dead keys 3.5 watts, swings about 5 watts. Pull out the noise blanker and it dead keys 8 watts and swings to 10 watts. I don't want to stress the radio so I use the lower power setting.
The D201A is easier to tune on SSB since the Crystal Selector can be used. I find the receiver VFO and clarifier more difficult to use on the Mark IV for SSB.
If you pick up a Mark IV carefully inspect the Molex plug that connects the transmitter to the receiver. They tend to get brittle over time and the pins have a habit of coming loose. The Molex can be replaced by a Jones plug for about $50.00. Also the PLL has a history of causing problems. This was Browning's first attempt at a PLL radio. They didn't quite get it right.
If you can find a Mark IVA, it used the Jones plug rather than the Molex, and the PLL issue was resolved.
I enjoy both radios, but I use the Mark IV more often. The squeal when I key the mic brings back memories.

Tube Rigs
Hi all, I am new to the forum. Looks like a good place to hang when the airwaves are dead.
I am a collector of classic radios. I have a couple of tube rigs that are enjoyable to use. Nothing like high level plate modulation.
My favorite being a Regency Imperial AM SSB DSB. Next favorite is a Cobra 98 AM rig, and then a Lafayette HB-400 AMer.
Looking forward to talking with everyone who also is hopelessly nostalgic for classic CB radio.
