The excellent results predicting the polar material content (adjusted R 2 0.997) was successfully validated with an external set of samples. These samples were analyzed to obtain their FTIR spectra and to determine the composition of fatty acids and the content of total polar compounds. A virgin olive oil was heated up to 94 h, and samples collected every 2 h constituted the training set. Then, the area covering 978−960 cm −1 was chosen to build a model for predicting polar material content for the particular case of virgin olive oil. The bands assigned to conjugated and isolated trans double bonds that are commonly used for the determination of trans content provided the best relationships. The IR bands changing during frying in sunflower, soybean, and virgin olive oils have been examined in their linear relationship with the content of total polar compounds, which is a preferred parameter for frying control. ![]() In this work, a method based on ATR-FTIR has been developed for monitoring the oil degradation in frying procedures. Also make sure to use thermal compound on whatever you use.The monitoring of frying oils by an effective and rapid method is one of the demands of food companies and small food retailers. just pay attention to the different pinout. One which looks good is the ZTX450, which is available at Mouser or Digikey. If they don't have it, then it would be wise just to sub it with something else. ![]() If you are going to try for an original check B+D electronics. So most of what you see are likely to be fake. The 2sd400 hasn't been made in years by the original manufacturer. I know plenty of amps use the 126 for that purpose. Others here might have different opinions, but I wouldn't use anything larger than a TO-126 case for that. Neither is it the one that's really suitable for that purpose anyway. Whoever installed it just used what was handy, because that's certainly not the one the original crosses to. It was put there to sense heat, and help keep things in order for biasing when the temperature changes.Īs far as the transistor is concerned, TCG is just an ECG/NTE knockoff brand. Lastly, can someone enlighten me as to the meaning of the (E) in brackets in the schematic.įirst, the manufacturer didn't put TR506 on the sink to dissipate heat. The replacement is not a TO-92 package and there is no stock mounting clip like the other channel (right).Īt this point what would you do? Leave the transistor that's there? Order a 2SD400 replacement and DIY a clamp? Are the clamps available anywhere? I couldn't find any. While doing the amp board I noticed some reconstruction and replacement of the Sanyo 2SD400P (TR506A) that's mounted to the heatsink (left photo). Since none of the components were the same as stock I decided to follow the EW's advice in this thread and go with On Semi replacements. Now that I've started I found one channel must have failed because there were a lot of replacement components. I played it a bit after I bought it but it sounded a bit off so I stowed it away until I was ready to do a full recap. I'm in the process of rehabbing this Realistic I've had for a couple of years. ![]()
