Fisher-500c-Vacuum-Tube-7591-Receiver-in-Near-Mint-Condition

eBay seller has 358 transactions with 100% positive feedback.  I paid $800.00 US  Copy & paste of what was done/serviced/restoration : (it's a bit long, my apologies)

 
 
From DECADES AUDIO we have a NEAR MINT museum quality example of the absolute best receiver ever designed and produced, the FISHER 500c Wideband FM Multiplex Receiver.  This particular unit was a one owner piece completely serviced and ready for plug and play by Fisher Technician Greg Kruk, who has fantastic feedback from hundreds of vintage fisher customers.   

The specs on the 500c are impressive. It's cost was about $390 in 1964, and Fisher considered the 500c as the "Industry Standard". It offers 33 RMS watts per channel, an exceptional FM tuner section with superb sensitivity, and a very colorful and layered audio reproduction with a beautiful true to life soundstage. 
These receivers were at the top of many audio reviews and still are to this day.

 

This Fisher 500c has been completely restored. For long term reliability, several key parts were upgraded. The selenium rectifier has been replaced with a new silicon bridge rectifier. The low voltage power supply capacitor under the chassis was replaced. The 5.6k ohm resistor in the low voltage power supply was replaced with a 3.3k ohm as a modification to the output tube bias voltage, now in the -19v range vs -17v stock. The high voltage rectifiers were replaced with Fairchild fast recovery effect diodes/FREDS. (600v-3 amp cont./100 amp surge,70ns). All of the smaller electolytics were also replaced with fresh new stock including the 1uf electrolytic in the FM multiplex section. To preserve the original sound characteristics, the original factory EROFOL II coupling capacitors have been left intact. These are excellent HIGH quality German made metalized polyester capacitors that were installed on later production pieces. Each were tested and still remain at factory specifications. All of the original Mylar/Polyester capacitors including the multiplex have been replaced with HIGH QUALITY Sprague 225P "Filmite E" Polyester film & foil capacitors. The output section has been upgraded with 10 ohm 1/2 watt Vishay Dale resistors on the cathodes of each of the 7591 output tubes. In the event of a catastrophic output tube failure, these resistors will open rather than destroying an expensive output transformer. These are Ultra premium HIGH temperature stable military grade resistors, not the cheap carbon comp type used in many resto kits. Voltages are kept within a tight tolerance under HIGH heat conditions. Also a CL-90 inrush current limiter was installed "like a mini variac" on startup. The on/off switch, capacitors, and output tubes operate under much reduced stress during initial startup. After startup this part heats up as normal and then reads out to "ZERO" ohms. IT DOES NOT hinder performance in any way.

All 12ax7 tubes have been selected for their various characteristics and tonal qualities in their specific locations. All have been carefully selected to be free of microphonics, and have closely matching triodes with test results exceeding 100%. Included in these are brand new production/matched pairs of excellent 12ax7c9 tubes in the phase tone section, 12ax7wa/7025 premium LOW NOISE tubes in the phono section. Phase inverter tubes are matched and Sylvania made. The rest are a mix of Telefunken and Mullard tubes. (Multiplex section)

This 500c has been completely aligned by one of our leading technicians. All FM tuner tubes have been upgraded with HIGHLY screened tubes. FM performance is SUPERB and distant channels are received with ease.

This Fisher 500c is in "VERY NICE"condition. The chassis and transformers are in BEAUTIFUL shape The faceplate lettering is excellent, the dial glass is beautiful with all segments and numbering intact. All original knobs are in pristine condition and complete with their brass caps. The AC cord is original and has the Fisher logo on the plug end. Their is a small blemish to the chassis metal near the power transformer. This may clean up but we'll leave that to the new owner. All dial lamps and indicator lamps were upgraded to new long life versions.

This beautiful Fisher 500c receiver with all its upgrades is completely plug&play. All features, inputs, and controls work perfectly. I have listened to this 500c for the past several weeks and it continues to function and perform excellently. As with all vintage electronics we sell, this item is also being offered as is, all sales are final. This 500c will be extremely well packed, so bid with confidence. Here's your chance to own one of the cleanest and best sounding Fisher receivers you will ever find! Thanks for looking, from "Decades Audio"!

Hi Tom,

 

Thanks, it is a nice unit.  The only aspect that worried me somewhat was all of the restoration done to it.  I owned a 500C last year & had it serviced & once I got it back something about it just didn't quite sound the same any more and remembered moodyrn mentioning on a post that restoration of the 500C should be done by someone who really knows what they're doing.  So eventually I sold it at a personal & $ loss.  In this case I trust that the restoration was done properly, the seller is very forthcoming with "if for any reasons there are any problems don't hesitate to contact me ...." & he also sent me pdf files of the amp manual & service manual respectively.  All in all : aesthetically it appears to be fine, it's been serviced by a reputable 500C specialist/ technician & the $800 US price was unbelievably appealing.  

 

So, I'll be posting my impressions as soon as I get the amp Tom.

Thank you SpeakerBox.  See my reply to TomNC above.  I just couldn't pass it up even though I'm basically broke right now.  

 

I'll have some explaining to do with my wife when the amp gets here. :rolleyes:

Also purchased this cabinet.  Some guy builds these for much less than older/ original & most times less than perfect looking cabinets for sale on eBay.

Headphone out is good........................but out of the taps it goes up a level or 3.   Glad to hear you're enjoying your foray into vintage!

Indeed! 

 

Gonna take my Sansui out of storage Labour Day weekend for 2 days and have a blast!

Hey guys, anyone have an idea what a Sansui 9090 that needs bulbs and a de-oxit treatment is worth? See one locally, but think he's asking too much.
