This used OPS-1MKV is in excellent condition though approximately 16-17 years old (educated estimate). This phono preamp because it has no matching stand alone Joule-Electra power supply, was meant to be powered via a LA-100MKIII (or possibly some early LA-150's too) with the external power supply connector on the back (I've attached a pic which shows what this would look like - you would need your preamp to have that connection on its rear panel). If you have a Joule LA-100, you know how nice the gear is and the OPS-1 phono preamp is a gem. I've recently gone through this OPS-1 using a customers LA-100MKIII to power it (as it has not been used in at least 3 -4 years) and verified it is in proper working order... this including testing and replacing several old/weak tubes with new, then spinning a few records with it. Its quiet and sounds very nice! Rated 8/10 for age - its condition is really that good!

IF PURCHASED AT MY ASKING PRICE, I will include a free checkup and test of your LA-100 with this OPS-1. You send me your preamp and I will hook them up and make sure they are working properly together, check  power supply operation, test all the tubes in your LA-100 (let you know of their condition) and bias your line stage to spec, etc. I have the factory specs and detailed experience and knowledge on the design and operation of Joule--Electra gear - feel free to research my rep on servicing/upgrading Joule gear.
