Phono EQ (small, inexpensive) ??? Two Phono Inputs???


Two TT For my office system (details below) (is that TTT?)

I need a dedicated phono preamp, small is best, inexpensive is nice. Nothing but RIAA phono eq is needed.

suggestions?

a. One phono Input/Two TT: I have an old very compact Sony video selector I can use (4 inputs, 1 out), then go to a single input phono preamp

b. Phono Preamp with 2 phono inputs, switchable or dedicated.

suggestions?

system:

Amp: Carver Cube m400t, 200 wpc, one input, zero controls, not even power switch

I actually ordered one (un-named/labeled) from AliExpress. The most popular one I read about was a company called Swagman, based I believe in China/Hong Kong, but after contacting them, they seemed to indicate they were having shipping issues since the virus. So I tried another option. Yes, via AliExpress it was also coming from China/Hong Kong, but they didn’t indicate shipping would be a big problem. So, I took a chance. It took about 10 days to get to shipping, but once shipped was here within a couple days. Not bad overall.

There are many folks selling various versions of these linear power supplies, so you need to do a bit of homework, and select a seller with a good rating. All which I did, and also asked some questions of the seller just to see how they would respond, and how quickly. I also selected one with an R-core transformer, as I understand a poorly designed toroidal transformers could create unwanted noise, and R-Cores are known to be typically quieter. There are a bunch of these out there, you just need one which comes in 16v.

The company who provided/built mine was called ‘SENGTERBELLE HIFI Audio World Store’.


Using parts from the non-working pair, and patience, I successfully got one of the Mitsubishi Vertical TT, LT-5V looking good and working well. Zero tracking error, extremely stable speed, probably due to the balanced Platter/Flywheel design.

It came with a Stanton 600 cartridge with ____? Stylus, unknown condition. Happily it played my sacrifice test LP nicely. Removable headshell, any 1/2" cartridge, IF 18mm height can be achieved.

Put my AT440 Microline on it. Great luck on size, it matches the 18mm height specified. Tracking weight needed help, I had to add 4g brass weight to the very light AT headshell to first get ’0’ then add 1.5g tracking weight via moving the weight 'out' which is forward of the pivot point in the vertical arm, couldn’t be easier.

Ridiculous how cool it is and how good it sounds, the automatic features I need for my intended use.

The Technics Vertical TT SL-V5 I didn’t get is limited to P mount, I like this better, and I will get another headshell/mono cartridge ready for this in my office eventually.

LT-5V is now running downstairs thru my beloved McIntosh mx110z MM phono and primary system. I love the sound of it. I use the Shure V15vxmr body with new Jico SAS stylus my main system. Audibly, they both are terrific, I always go with the Shure over the AT, due I am sure having a pre-disposed functional bias toward Shure’s brush. Jico stylus has a brush, but it is not ’stabilized/dampened’ like the Shure brushes are.


OK, best I can figure out so far:

Two TT, single phono preamp (avoid separate A/B switch)

MM AND/OR MC seems to be the solution.

single switched input or two separate inputs individually selected

rear or front switching
.............................................................

most phono preamps that include both MM and/or MC have a single input, and a switch to send that input to it's internal mm or mc. Single TT only,

some phono preamps have two separate inputs, MM and MC, allowing attachment of TWO TT, you select which input/which TT to use via switch

Location of switch is most often in the back, a few have front switch to choose which input to use.

.........................................

These three have front switch to make it easy to change and remember where it was left.

Soooo, I can use P mount MM on the Technics Programmable Compact, SL-J33, seller took my $90. offer for this 'fixable' one

and use 1/2" MC on the Mitsubishi Vertical LT-5V. Swapped with Bill, got one working wonderfully, mice had their way with the other's wires. I was blasting it in the main system yesterday, it is amazing technology and sounds as good as your cartridge. I will need to move it to compare it's linear tracking to my 12'5" long pivoted arm. (very similar cartridges, Shure SAS/AT ML

reminder, 2nd office system, often just proving cleaned LP's for sale have no problem. It will be accessible while starting LP, but it will be blocked by my monitor, so looks are not important in this situation. 

reasons not to go for $75. unit?????
