Pioneer Spec-1 Preamplifier Professional Restoration Service

Description

This is a service auction for a Pioneer Spec-1 preamplifier you own. This is not an auction for an item for sale.  I have been repairing Pioneer components for over 30 years now and I believe it's time for owners of the Spec-1 preamplifier to think about a restoration. The capacitors inside the unit are over 40 years old now and in no way are they performing as new and your sound is definitely suffering because of this. All of the small electrolytic capacitors will be replaced with high quality brands like Elna Silmic, Panasonic FC, and Nichicon Muse. The larger ones on the fuse board almost never need replacing unless there are blown fuses on the board..............in that instance they will be replaced. Most of the transistors are generally good for the life on the unit but I do replace the noisy 2SA726 ones on the tone board. There are some scenarios where the negative regulator will die and this puts DC on the output jacks and could cause your power amplifier to trip it's protection circuits. These will definitely be replaced if they have failed. I also treat all the controls with De-Oxit D5 spray and this treatment lasts a very long time...............I've not found a better cleaner/lubricant. I don't have replacements for the rotary controls or knobs so if your unit is in need of these you'll have to source them elsewhere. You send your Spec-1 to me and the return shipping is included in the price. Please check my feedback and buy with confidence. My turnaround time is usually the same week your unit gets here.
Auction good for the continental US only (due to new insurance and shipping regulations)
Free return shipping is through Fed-Ex so make sure your profile lists a physical address. I do not ship to P.O. boxes through USPS
