78's through the system

I am simultaneously considering ways to upgrade my phono setup, and be able to play 78's on the big rig for the first time. I own a mid-80's Technics SL-1200 with a Benz-Micro Glider M2 going though a conrad-johnson PV-8 w/phono. The first thing to address is either modifying the TT to play 78rpm, or preferrably upgrading to a better TT that can do 78rpm. I have seen that Michell can supply a 78-capable pulley for the Gyrodec, but other suggestions would be welcome. Then I need a tonearm with a removable headshell, and I'm thinking SME, again suggestions helpful. I have no idea what 78 cartridge to look for (I'll keep the Glider for 33/45). And lastly, how imortant will it be to only have RIAA EQ available to me, or will I need to do something in the phono preamp area about that? My entire budget for this project is $3,000 max, whether I go new or used.

Hi Z: Appropriate cartridge for 78 is ceramic. A detachable is an idea -- but you'll still need to get the geometry right as different cartridges will have different dimensions...
As far as I know, RIAA eq. will do for post WWII 78's...
However, many 78's are best heard at speeds other than 78!! So, adjustable speed facility (with a display if possible) would be VERY useful!

Rega makes a 78 rpm version of the P3 and possibly the P2. Perhaps one could even economically convert a standard P3 or P2 to 78 rpm by changing one or both of the pulleys. Although the P2/P3 headshell is not removable, Gregm correctly points out that, with a removable headshell, you would still need to change VTA when you change to a different headshell/cartridge, which is not exactly convenient.

For $3K, you could get a used P3 AND a Michell and have a few dollars left!

Hi Zaikesman. How many 78 LPs do you own? How do they compare withh the 331/3 LPs? Are there some great sounding 78s? My parents have quite a few. Thanks for any reply.
Best regards
