@robelvick sorry, but i thought you have SL1000 MK2 http://www.thevintageknob.org/technics-SL-1000MK2.html But now i see you're talking about SL1200 MK2 :( Unfortunately you can't use any of the EPA high-end series of tonearm on your DJ turntable, because those arms are "10 inch, while the stock arm on your turntable is "9 inch. The spindle to pivot distance is different, there is no room for the EPA tonearms. But you can use SME or Jelco with ease. |
@chakster
Thanks. So now I need to know if the EPA-100 can be used without an additional armboard? ha. |
|
I have a Sl-1200mk2.
Wondering if the EPA-250 can be used without having to change the armboard.
Thanks |
When I need a wand, I now know who to pester, @jpjones3318! Cheers,

16, but one is a partial I bought for parts to fix two others. I've two bases as well. Fantastic system. |
Funnily enough, I had put my A500 up for sale. Now I am reconsidering. You've really got 15?!
|
Careful Lew - that's what I said 15 armwands ago! |
Thanks, guys.
@lewm If I run into anyone selling one of those A250 wands, I will point them in your direction. Cheers,
Spencer |
Sorry, that's "A250" arm wand. There I go again.
|
Sbank, If JP says the two are identical, you can "bank" on it. However, if there is a problem, any good machinist can make you what you want if you give him the specs. One guy is Colby Lamb out in Oregon. He is an audiophile/machinist par excellence.
After 40+ years, I think I know everything there is to know about what equipment was made by whom and when, but every once in a while I have an epiphany like this that reminds me I really don't. Now I just need to find a B250 arm wand for MY B500 base. |
Yes, the aux weight that came with the EPA-A250 is identical to the aux weight for the SL-1200MK2, et al.
|
@lewm It's amazing all that there is to learn! Just today I went through a panic when the seller told me basically that there is no room on the EPA-250 for an "additional weight" and that the arm I'm buying only has one weight. I sent him pdf of the owner's manual showing him figure #17 which shows the "additional weight" which screws into threads on the back of the main weight. Meanwhile while waiting for a reply I found weights for sale but most were described as for SL1200 and costing $10 or less. The lone vendor with an EPA250 weight wanted $40 and weeks of shipping from Japan.
Lo and behold, the seller saw the pics, confirmed that a) He does have the weight to send me and B) Yes 100% interchangeable with the SL1200 weights. Lesson learned. Cheers,

Thanks to your post on VA, I found out after decades of ignorance that my Technics EPA-500 tonearm is actually identical to a Technics EPA-250, save for the nature of the arm wand. So, thanks for bringing up this question. |
Lew,
I appreciate your comments and concluded as much from the other commentary from the esteemed John Elison, our friend (also esteemed!) @dgarretson and yourself. Given the flexibility of this arm I should be in good shape with all the carts under consideration and most others. It's not going to be a constraint. Cheers,

You got some pretty precise responses over on Vinyl Asylum. Mine was perhaps the vaguest, but I stand by my opinion; the equation(s) used to determine tonearm/cartridge matching may give precise numerical answers, but the data inserted into the equations is always a bit shaky, always an "estimate" or based on a manufacturers published specifications, which may or may not describe the characteristics of your particular sample, especially where cartridges are concerned. Furthermore, the range of acceptable results for resonant frequency (at the very narrowest, between 8 and 12Hz), actually permit a fair amount of latitude in effective mass and compliance, especially when you consider that F is a function of the square root of the product of those two parameters. So, I say go for it, provided the compliance of the cartridge and the Meff of the tonearm are even in the permissible ballpark of a good match. Far too much time and effort is spent worrying this subject to death, again, in my opinion.
