We have assembled a new RM-9 Collectors Edition that covers both the MK I and MK II. There are now 22 pages of text, 4 diagrams and 5 pages of product literature and reviews. Included are service notes, a block diagram of signal flow, a schematic and PC board layout with all the parts values and a schematic showing the modification of the power supply from the MK I to MK II where we add chokes and additional filter caps. These parts are available.
The new manual is $35 plus $10 shipping. Although the shipping may show up higher on the tube store, we will correct it when we charge your card. As always you card is NOT charged automatically but done here at the time of shipment. You can always add things like fuses in the comments section. Fuses are $3 each or 10 for $20. These are high quality fuses and better than Tuning Fuses as they will provide the proper protection.
