Magnecord PT6-V schematic needed

[Studiogearlover]

Hello Guys

Please let me know if any of you has the above schematic by any chance. Its not coming up anywhere on the web. The PT6-V was part of their "Voyager" line together with the usual PT6 tape transport... i see all of the other Magnecord amplifiers everywhere but not this one. This has 6x4 rectifiers instead of 5y7 and 12au7/12ax7's. I would be really grateful if you could help me out here. Attached a related article, but no schema sadly... Thank you !

I don't know who drew this to give them credit, but here is a version someone traced in 2011.

No sign of a bias/erase oscillator in that schematic. Is there a page missing?

Cheers

Thank you so mush for this... exactly what needed. Really a big thanks !

hi Ian... i am no way an expert on this but I think the bias circuit is on the matching tape transport...Pt6 and so on... although I could be wrong...

You are right. More detailed reading of the brochure reveals the transport is equipped with a 12AU7 bias/erase oscillator. A good idea to put it close to where it is needed.

You are quite welcome! As I said, not my drawing, but someone did a nice job

I used one of these on a daily basis for 14 months while I was a Broadcast Specialist in the U.S. Army. Great machine for editing. Very rugged and sounded good for speech recordings of Home Town Interviews. Tubes checked on a regular basis and never had to replace any of them. FWIW.

They did do a good job, I have some schematics I need to draw up from pencil scribblings. What is the simplest method to do it on a computer? Not looking to spend money on a program but a free program would be good. I am pretty sure it will have been discussed many times already a lead or a point might be useful thanks...

Cheers... yes, its a very neat drawing. .... I hope you don't mind me taking the opportunity to ask but by any chance... would you have a Magnecord P75 tape transport schema too? I am trying to hook the PT6J and the P75 together... there are several years apart of these units but I am hoping that the base design will be the same. I only have the P65 schema but not the P75.... thanks again!

Sorry, I do not have that one in my files.

[What is the simplest method to do it on a computer?] -- On this forum, your best bet is to use the -- FREE -- CAD-design program called "KiCAD". This software has both rather full-featured schematic and PCB design programs built into it and they are also relatively easy-to-learn. Here is a link to download the full program:

https://www.kicad.org/download/
On both the KiCAD website and on the Digi-Key website, you can either download or watch several complete series of training videos that will show you exactly how to use each section of the software in bite-sized videos that are each only a few minutes long. Here's a link to a series of Digi-Key "KiCAD" training videos:

Should you need some assistance in getting yourself started with transferring your schematic pencil scribblings into a CAD-designed schematic, create some very clear scans of your scribblings and e-mail them to me. I will get them started for you and then you can go about learning how to finish them up. Sound like a plan??? Then, as you learn how to use the KiCAD schematic program, the training videos will teach you how to transfer your schematics over to the PCB side of things and then you can learn how to design your own PCB's. Sounds like future fun, doesn't it??? GET YOURSELF STARTED!!!
