Just gorgeous, timeless classic. Reason I keep my 1200B last one made in USA. Very informative video! Lots of cool tools there.

Beautiful pieces. What a privilege to get to work on them and bring back their original sound and features with modern parts. Please tell me that you played your favorite music through them for two days straight after verifying their power output. 🙂

interesting video. The u1f film cap bypassed with multiple smaller caps is quite common today. Several of the high end tube manufacturers now do this.

The gain control on these was never meant for a source to be connected directly to the amplifier. It is a linear pot for one thing. For the best signal to noise ratio the manual indicates it is best to always keep the gain at maximum. The control is particularly useful when checking or adjusting bias and also to protect the amplifier and speakers when connecting a preamp for the first time or a device that might be noisy or have DC at the output...

Thanks for this Video! ...I have a pair of these Monoblock Amps that I inherited from an old friend of my Dad's ...He thought that an output transformer was faulty, which turned out to be aged Electrolytic Caps in the Power Supply. I really need to dig these amps out of storage where they have been for almost a decade. I want to go thru the amplifiers and replace all faulty or failing components like you have just done in the video.

Quite possibly the most comprehensive presentation of any vintage piece of tube audio gear that I have ever had the pleasure of viewing! What brand were the output tubes? Did you know the date of manufacture for each unit? Perhaps you already know this, but with the 8-B, the factory date of manufacture was often stamped on the reverse side of the bias meter housing, hidden beneath the brass retaining strap. Again, thanks!

I am glad that you enjoyed watching the video. Thank you for the tip on the manufacturing date. I will keep that in mind for future documentation when 1960s Marantz amps come in. Finding two matched quads of NOS EL34 was going to be tricky, it either take a lot of hunting or a lot of $$$. After speaking with the owner, we settled on current production EL34EH, the Electro Harmonix with the green label. Those are the tubes that were loaded during the bench testing.

Greetings from Seattle. Incredible video! Yohu are te Model 9 genius. I have six of them, They have been worked on over the years, but no one of your caliber has worked on them. Obviously only the most skilled people should touch a Model 9. Do you offer repairs, restoration? Thanks!!
