However, given that the 27 tube is essentially an IDHT version of the 26 tube, I am beginning to think that I could use the 26 design (except for the heater supply) with the 27 tube. I would then use ac for the heaters and use Ale's suggestion to add a 1K5 resistor in the cathode with its decoupling cap, remove the battery and C1, and change R1.

There's no inherent reason it has to be junk so I'd be interested in any test results, please share if you know of any.

The preamp schematic is based around a common 12AX7 dual triode. The line level (Hi-Fi) version of the schema has the gain set at 4 (6 dB). What makes this kit very good is is that it is have tone control and hum balancer. The scheme comes from the process of scanning old HiFi schematic books. For those interested please contact us to get the copy. This is unquestionably a tube preamp, but it is very quick, detailed and extended. To the issue of gain, it is about as loud as I like it at 12:00 or 1:00 on the volume pot so I have all the gain I need with the external cross-overs and the Linkwitz.

My next project is going to be a valve power amplifier and I'm interested in building a circuit that uses 300B valves. The attached circuit is one that I found over on DIYaudioprojects. I'll probably use a similar filament supply to the one in my 01A preamp, with Coleman regulators, rather than the one shown here. Combining advanced leading-edge process technology with state-of-the-art circuit design, the LME49720 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. The LME49720 combines.

The preamp can be made to work with other supply voltages, but you will find yourself adjusting resistors and also needing a distortion analyzer to set the Nutubes for the desired distortion character. Easier to use 24V. If you use a linear power supply, you will want to have it regulated, as we need a constant DC value regardless of AC line. The $1485 PV-5 is a "budget" version of C-J's $2850 Premier Three preamplifier, but according to the manufacturer it embodies much the same kind of circuitry. Tubed preamplifiers have a well-earned reputation as system busters. Many of them during warmup produce horrendous bangs or plops so severe that every speaker fuse in the system blows.

This is a HiFi pre-amplifier circuit diagram with low noise output. Very wide range frequency from about 10Hz until up to 100Khz will be gained by this preamplifier for maximum audio performance. This circuit uses BC550C / BC560C transistors as active component. Use regulated power supply 15VDC for maximum result. It should be noted that the circuit works fine without the output transformer if a balanced signal is not required and cable runs are not long. The output transformer is a step-down (4:1), and will drop the amplifiers overall gain by -12 dB. Without it, the amp will have more headroom, but will lose some of the desirable tube compression. #HiFi #Amplifier #DIYHiFiAMplifierHave you ever wanted to build a DIY HiFi amplifier?

The schematics below show the both the Grado RA-1 and CMoy headphone amplifiers. Both the Grado RA1 and CMoy designs use a basic non-inverting amplifier circuit using an operational amplifier (opamp). For my CMoy, the opamp used was a OPA2132PA (Burr-Brown) which retails for about $5 and for the Grado RA1 uses a JR4556 that retails for about $0.50. Amplifier Construction .
