1977 OE hitachi radio MOUNTS

[Dave WM]

I am piecing together an OE stereo radio for my Z I have the radio and the METAL face plate, the plastic face plate is on the way. I have a switch I hope to get locally, really only need to source the mounts that bolt to the radio. I have the U shaped mount that attaches to the console. I did not want to piece this all together but seem the only way to get a complete radio with out spending a fortune on it.

here is what I am looking for. one is a simple bracket for just the radio, the other mount to the radio and provides a mount for the antenna switch.

how good are you at fabrication? To make up a crude set wouldn't be that difficult.  If you don't want to do that then, i'de suggest buying one of those $150'ish 280 radio's on ebay and rob it for the mounts and put it back on for the same price you bought it for Maybe clean it up a bit and offer SANE shipping costs.  Some are crusted with dirt and body oil ack... 

 Most people sell those with the radio's unfortunately.

I may go that route, but the fabing is more like it. Oh just read the other thing, check it.

Dave, you da man. I put in the 2 diodes and a 222 mylar (0.0022)  from my old hitachi radio graveyard and auto tune came to life

Now all i gotta do is track down some Steppenwolf and Deep purple 8 tracks and I'll be rocking out 70's style.

I think i owe you some radio mounts for your 77

Oh cool! It was getting late and I had checked out before you got there. If there is still no signal getting thru for it to lock on to, I would suggest signal tracing. Hard to do with no schematic but you could just start a the coil/tuning cap and go from base to collecter of each transistor that seems to be in the path and see where it drops out. You will need to start by tuning in a strong local channel for the tuning tank circuit to pickup.

I didn't have an antenna attached is the reason it didn't lock onto anything.  I wanted it to do continuous scanning because this thing has probably been sitting 20+ years and there are A LOT of gears that turn when its scanning.  I also faked an 8 track tape being inside and the motor turns and it changes tracks like it should.  I had it on for quite a while and if the function of that cap is to filter out the current from the signal pulse, shouldn't that cap be getting a little warm from filtering out the 8 volts?  It's not warm at all.

not sure about it getting warm or not. Generally speaking I would expect not. Glad to hear its working, that auto tuning is a trip.

The legs that hitachi put on most of the components is a strange design and they're a bear to try to solder to. I ended up just removed them and soldered the components directly to the board.

This thing is built like a brick sh!thouse. Weighs a ton.

 Comparing an earlier one to a later i've noticed differences in the radio pcb.  On the older radio there is a 472 green mylar whereas on the newer one (mine) there is none.

Could this be the mystery cap? On the older radio there is no pad or wires (lower left hand corner)  for the auto tune circuit.  Top picture is older radio

bottom picture is newer radio (mine)

Almost forgot. Gotta clean this  label up to print some new ones. This is going to be LOTS of work.
