Dear SirMy name is Ajayakumar. Please enter a number less than or equal to 2. August 31, at Your email address will not be published. First the clipping point is found at a 1 kHz sine wave and the output voltage noted down.

The VDC supply for the screen grid was in my first layout tapped through a resistor from one of the capacitors in series for the high 6p45d, this unbalanced the power supply greatly and I made a VDC linear 6p4s5 regulation directly off of the high voltage.

6P45S = EL509 = 6KG6 tube. Output tetrode

So now we have a self-balancing circuit without the need to hand-select 12AX7s, also a very high impedance current sink in the cathode circuit, and also a form of local feedback within this stage to improve balance.

The main reason for building a new set of amplifiers came with purchasing a set of old studio monitors, the legendary JBL Working with electricity is dangerous, all information found on my site is for educational purpose and I accept no responsibility for others actions using the information found on this site.

This damped the signal by a great magnitude but the parasitic oscillations would still occur. When searching for a amplifier design to follow, I came across a Hungarian article on rebuilding a old amplifier called the APX Upper -3dB point is found by turning the frequency up until the output voltage is 0.

The LTP avoids both these issues, but performs acceptably only when operating into a constant current sink. Hey Mads, Please check the attach.

Hi Istvan I found out that my distortion problems is mainly from overdrive of the input stage, my input sensitivity was as high as 70 mV in for 50 Watt out.

You’re covered by the eBay Money Back Guarantee if you receive an item that is not as described in the listing. A constant voltage at the base of a bipolar device translates into a constant current at its collector, given a high beta.

This seem to be the best range for these tube, and I think that it is the same for 6p45s too. As soon as input voltage came above VAC, the speaker would suddenly click and the fuse for the high voltage would blow.

So the power through is around 63 Watt and taking losses and rounding into account, it is fair to say this is a 50 Watt amplifier at low distortion. Very good balance indeed! Back to home page. Dummy load was a 8. Explanations are written on each screenshot from the oscilloscope. In this case, the voltage at the junction of the k will be an AC signal, out of phase with the input signal.

The first issue was a small 6p45 of the signal line 645s coaxial cable that was not shielded. The seller won’t accept returns for this item.

The second shows the effect of touching the isolation on the part of the signal line in cable that was not shielded. As I wanted to build mono blocks I contacted the company that originally made the transformers and had a second identical power transformer constructed at a very reasonable price.
