Phono preamps were a very mature technology last century when I stopped messing with them. A relatively inexpensive modern op amp can far exceed the performance of typical MM carts. Tubes seem attractive for other than performance metrics. Ricardus Well-known member. I'm pretty sure Pete Millett has a tube phono preamp. Let's have a look. Post reply. Insert quotes….

DIY Hi-Fi Phono Projects - Turntables, RIAA Preamps

A phono preamp aka phono stage raises your turntable's output to make it compatible with modern amps. At the same time, it adds standardised equalisation. So why do you need one? Your turntable either doesn't have one, in which case you won't be able to play records without one. Or maybe you just want to upgrade its sound beyond what's possible with the built-in preamp.

Sign Up Now! Very suitable MM turntables, greatly upgrade your sound quality. Each batch of components may be a little different, but the quality and performance is the same. This is DIY Kit, need you have electronic technology and detection ability to solder all components. We are not responsible for man-made damage.

This project is a departure from that of my normal sort.

This is an all-valve DIY 12AX7 and 12AU7 phono amplifier kit that enables you to use your moving magnet record player with your integrated amplifier. Similar concept to all designs in our Classique range, this DIY phono amplifier uses traditional design and topology which have been used and tested for many decades. You will only need one phono PCB per amplifier to power both left and right channel. We designed this DIY phono preamp kit to be in the exact same size as all other kits in the Classique range. The mounting plate , which can be ordered separately, will enable you to setup the kit as we designed it. It is worth noted that designing a phono amplifier in general is pretty tricky due to its nature.

In an update from it was pointed out that for some unknown reason, some suppliers no longer stocked 82nF capacitors, and several constructors have had difficulty sourcing them. There is an answer, and it actually improves the EQ accuracy albeit marginally. If the ohm resistors are not available from your supplier, use 2 x 1k5 resistors in parallel. Alternatively, you can use the originally specified 82nF cap with a ohm resistor. The worst case error with any of these networks is less than 0. The original network was used before E24 resistor values became commonplace ohms is an E12 value, which used to be all one could get easily. RIAA equalisation is the standard for vinyl disks. It's been in use for a long time some time around , and was 'tinkered' with by the IEC to tame the bottom end.

This project also shows a DIY build that anyone can follow to make his or her own preamplifier. The op amp IC came from a salvaged board; however, there is still some old stock online. Although I have not tried it, almost any general-purpose frequency compensated op-amp IC has a chance of working in this circuit. You can also use an op amp with FET input in which case you will not require C3.

Riaa phono preamp kit. June 14, It is useful for connecting products with magnetic pick-ups such as turntables to an amplifier. Gain is 47db at 1 KHz; 67 db when used PH premium phono preamp KIT This is a premium grade phono preamp with several enhancements in the circuit design and power supply. How To Install.

This page contains equations and a procedure for accurately computing the circuit component values for a phono preamp using active RIAA equalization.

Hey Stu, just made this from your vero! Thanks for the time invested in drawing it up, Honestly I can't believe it worked first time, and without a chassis! One thing to note for people making this, a few of the values didn't correlate to the vero, just a few typos. Thanks again! Hey Joe, thanks for popping in. Glad to hear it worked! And thanks for the heads up about the values.
