I have aquired a Grace g-707 that has been trashed and I'm restoring it. The metal parts of the arm are in good condition, part of the anti-skating assembly was cracked, but repairable, but the headshell is completely missing.
So what I want to do is 3D print a replacement headshell. Using images on the internet I can get a pretty good idea of the geometry, but for accuracy I need actual measurements. Is there a g-707 owner out there who can get a ruler, or better yet some calipers and give me the dimensions? Only need the headshell, not the arm. Here are the measurements I need (in rough order of priority):
width length max depth (at the back) min depth (at the front) outside diameter of the arm mounting tube length of the arm mounting tube distance from front to start of screw holes length of screw holes width of screw holes spacing of screw holes (should be 1/2", yes?) thickness of the plastic lastly, if you can measure the angle between the arm and the headshell that would be great.
You can refer to the image to see what I'm talking about. If you can't be bothered doing them all then just the length, width and depth would be a great help.
My previous power amp I always just got it biased by the people who sold me the tubes and have to admit to have never adjusted them myself afterwards being scared to touch it while it was running.
My new power amp came with instructions for biasing the valves and a tool to do it with. I checked the bias shortly after installing it and everything was nigh on perfect. After reading a reviewer say he checks tubes at 0, 100 and 200 hours, I then checked it again after 200 hours clocked up on the tube counter and most had drifted down slightly (.5-1mV) and I adjusted it. That's certainly not enough for a noticeable sonic difference and while I've read lots about how often the bias should (or should not be checked), I'd like to hear from others with tube amps regarding how often they check their biases.
Hello fellow SNAers,
I've got a working Yamaha CA-1010 amplifier that I would like to have it recapped and brought up to spec to ensure that it will last me some 30+ years into the future without any major issues.
Could you guys please give me some names of people who would be capable of performing this kind of service? I would prefer if this person was located in South Australia in order to avoid having to post this 20kg amp interestate.
I know that there are some great members interestate that are used to do this kind of service on a regular base, however it would be fantastic if we could find this kind of professional here in Adelaide SA too.
Please let me know your thoughts and thanks in advance!
After some don't know how many years, 10?20?30?...what a feeling!
I have a beautiful Braun SK55 that I picked up at a garage sale several years ago. The tonearm is damaged and someone has made a poor attempt at rewiring. Does anyone know where I could source a new tonearm or recommend someone to chat to about getting it fixed in the Melbourne area.
