I'm having a showdown between the GE 3-5259A and the Panasonic RX-5050.

These two boxes tend to be the radio I grab when I don't want a huge amount of weight but a decent sound. The JVC M70 is in the general mid-size range but it weighs much more and is in another class in regards to power output so it is being excluded. These two models seem to be the best match in my collection for a showdown.
Panasonic
Pros:
I like the EQ on the Panasonic. It feels lighter to me than the GE. It's obviously a little smaller which is great when going on vacation and every square inch of vehicle space matters. It has a full motor driven transport with feather touch controls. It is a decent performer in the AM/FM category. It goes loud and is easy on batteries. The best thing about the Panasonic is the Ambience. Turn that on and the radio really comes to life. One of the best I have heard. It has the typical Panasonic tradition of being dependable and reliable.
Cons:
Not as crisp on the highs as I would like. Has a slightly hollow sound to the mid range to my ears. Bass rolls off quickly. Tuner needle has lots of play in relationship to the tuning knob on the side. Only has a single VU meter LED output without tuner/battery strength indicator albeit the power LED will dim when batteries are low. No music search but you can cue up your song manually. This is being picky but I'm not as much of a fan of knobs and switches being on top. That's just another place for dust and dirt to find its way inside. While not part of this showdown, I'm looking primarily at you JVC M70
GE Blockbuster
Pros:
What's not to like? It's aesthetically pleasing. It has decent AM performance and awesome FM performance. In the right atmosphere it sounds really good with warm bass and the treble is crisp. It also has excellent mid-range. Dual VU meters that are there with purpose - signal/battery strength / input signal strength. High end full motor driven transport with music search (3 songs forward/backward). It's a solid machine with knobs that are smooth and the tuner needle is precise as you move it up and down the scale.
Cons:
Suffers from a few design flaws. The head assembly and idler gear are the main culprits that are prone to fail. Another common issue is sticking VU meters. It's easy to distort the bass at higher volumes (5/6) when the bass is at max (mine might need caps). Stereo wide feature is nowhere near as good as Panasonic's Ambience. I mainly leave it off. The music search feature automatically engages when you simply want to cue a cassette back just a bit - very annoying. There is a workaround for this.
So which one do I like better? I enjoy them both for different reasons. But, if I had to choose between the two I would take the Blockbuster's features and overall natural sound and build quality over the Panasonic. Its components may not have held up over time as well as the Panasonic, but it makes up for it in performance once you get over the hurdle of it's common failures. The Panasonic still has a place over the GE. It has held up better over time and it kicks the GE's butt when you turn on Ambience. The sound just floats around you in the room and it can actually over power the GE with this mode on. It's unbelievable. Despite this, it's not as solid as the GE. Knobs and sliders are a bit wobbly with some play in them. So fit and finish goes to the GE. Plus the GE has metal speaker grills where the Panasonic is a single molded piece of plastic to look like a grill. You can't really see the speaker like you can with the GE. What's not to love about those huge chrome dust caps?....even if the voice coil underneath isn't but the size of a nickel
So, earlier I was talking about the Blockbuster's MLS auto engaging and that being annoying (Con). Unless my unit is malfunctioning, this is what I mean. If you are playing a cassette and you simply want to go back and hear what the lyrics in the chorus were without rewinding to the beginning of the song, you have to stop, rewind and then press play to do that. If you press Rew/FF at any time during playback, the MLS automatically kicks on. It lights the number 1 LED on the MLS panel and then proceeds to FF or Rew to the beginning or end. One would think that it would simply Cue the tape unless you press the MLS button at the top to light the LED's and turn it on.
Good thing is, I found a workaround for this. If you lightly press another function button to where the tape function pops out but no other function button locks in, it still outputs the cassette for audio playback. You will need to turn the volume down to not get blown away from the high pitched sound but, at that point the MLS is turned off and you can then Cue back or forward within a song without the MLS system taking over. Maybe some of you that have had a Blockbuster for years might confirm this with your radio
If so, maybe I hacked a new unlocked potential that has yet to be discovered with this model.
