Re: [Drakelist] I've got a job ahead of me.

I was going to go there just for the manual.  I rarely add mods to a radio unless I can see a distinct advantage for doing so - putting in a higher-wattage resistor for a known long-term heat-related issue comes to mind.  In working on this receiver, I will first be making every attempt to get it functioning as it is. I appreciated the reminder for the site.  Garey also emailed me a pdf, so I might not need to download anything else (but I'll check anyway). My first scan of this board has revealed to me that much of it is the power supply for the entire receiver.  I'm wondering just how much ALC circuitry is on the same board.  If many of those 18 or so 26 AWG wires are just powering other small boards, their connection locations may be less critical.  Again, I'll have to rack my brains a bit on the drawings to figure out where all the wires go. TNX to all for responding - this is my first SPR-4, so all comments are welcome!

Please be aware that all the mods at that website are not necessarily advisable, because of damage to the equipment, compromised safety, or ineffective results.  I've gave up on that website when I saw things like "remove the heat from the L4B power supply by taking the 50K 50 wt resistors out of the circuit".  Well, yes, it does reduce heat, but it also removes part of the bleeder resistor network and it also disables the ALC function.  Thanks, but no thanks. On a more positive note...Happy Thanksgiving!!!!!!!! -----Original Message----- From: Gypsymt34 <gypsym...@aol.com> To: w1es1982 <w1es1...@earthlink.net>; drakelist <drakelist@zerobeat.net> Sent: Wed, Nov 23, 2011 3:21 am Subject: Re: [Drakelist] I've got a job ahead of me. Hello Steve,    w1es1...@earthlink.net writes: Does anyone have more information on which components are mounted on this board? FWIW   modsDK   http://www.mods.dk/view.php?ArticleId=3237 has  three pieces of information on an SPR4  The owners manual which had a schematic and the service manual.   The latter is shades of a TR7 manual ( I am told) in that you had parts lists and numbers, portional schematics, and pictures with parts labeled. Along with full schematic.   There was also a separate schematic which might not be a bad idea in that you could take it and digitally have it blown up and printed at your local Kinko or print shop.  Problem on modsdk if you haven't used them is that you can only pull a free item every three days.   They also showed two modifications its a separate list. 73 and have fun,  Carl wd8nhk   _______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
