Welcome to Showtrade® Pre-Listing Services
Here's your chance to view up and coming equipment that has yet to be listed on The Showtrade Outlet eBay store. Some equipment is in the process of being repaired while other pieces are awaiting appraisal. If you see something you like send us an e-mail with your best offer and we will forward it to the owner for consideration. You could be the next owner of some of this classic equipment before it hits the market!

Urei 1176 Ln Silverface |

|
The output stage of the 1176 is a carefully crafted class A line level amplifier, designed to work with the (then) standard load of 600 ohms. The heart of this stage is the output transformer, whose design and performance is critical. Its primary function is to convert the unbalanced nature of the 1176 circuit to a balanced line output, and to provide the proper impedance matching to drive the line impedance of 600 ohms. These two jobs are accomplished by the primary and secondary windings whose turns' ratio defines the impedance ratio. This transformer is critical due to the fact that it uses several additional sets of windings to provide feedback, which makes it an integral component in the operation of the output amplifier. Putnam spent a great deal of time perfecting the design of this tricky transformer and carefully qualified the few vendors capable of producing it. Initial benchtests reveal: This unit has a cracked ratio button which causes it to occasionally fly off when switching between compression ratios. Item is scheduled to be repaired for listing on Ebay. |
