The 1580 that I purchased in 2008 has been working great since day one. However this past year (2013) it had slowly developed a hum in the left channel. Because I value this machine so much I decided it was time to send it out for a complete restoration. The machine was shipped out to an Electronics Technician in Florida. The machine arrived at his house, only to have been damaged in transit. Apparently my packing skills were not up to par. The Technician (who will remain nameless, as not to bombard him with restoration inquiries) assessed the damage, and indicated he would be able to repair those parts damaged in transit. Well that damage basically amounted to 12 hours of labor to get everything correct. The Technician, as you can imagine, was ready to pull his hair out! The next part of the restoration involved repairing the amplifier section. Upon inspection the Technician was able to verify the hum I had been hearing was indeed in the left channel, and would require replacement of the electrolytic capacitors. In fact the entire amp section would need these caps replaced. Well the fun didn't stop there. The Technician discovered other various issues with the amp section. The power supply was part of the problem, but he also suspected possible issues within the "Network". We discussed various solutions over the phone, and decided he would go ahead and swap amplifiers. I was lucky in that he had a "donor" 1580 parts deck. The headache didn't end there either. The erase head was also having issues and it was decided to go ahead and replace it. What other parts did my wonderful Technician replace? The following; the main capstan belt, counter belt, reconditioned all rubber idler wheels, and cleaned the entire chassis, plus lubrication of all necessary parts, etc. he also installed a better fan for cooling the internals of the 1580, as well as new motor mounts. Basically he cleaned every nook and cranning. At the end of this restoration my Technician decided it would be in the best interest to build a custom crate in which to safely house the 1580 for shipping it back. Photos of this crate, and of the restoration can be seen below. I would like to personally give a shout out, and a thank you here, to the technician who painstakingly restored my 1580 back to new! His attention to detail, and his commitment from start to finish can not be fully expressed into words. Let me just say when the machine arrived I was in awe of the packaging that he did. Also I must clarify, the 1580's cosmetics were disassembled to avoid damage while shipping. I am glad this step was taken as there's no telling what kind of damage might have occurred had I sent the entire machine. When the machine came back to me I reassembled the outer casing, and other various parts. When I put on the first tape I was blown away! It's never sounded so good! It was money well spent. So as you can see this was a major undertaking, but as I stated well worth the effort!
