We parralelled the rectifiers only after derating them to 80% of there full rating. At higher power levels the amps operated in Class AB mode. so the amplifier were working as ifv they were running in Class A mode. At low power the bias was higher than normal. The 1 ohm with the parralell diodes was used in the Class A amplifiers. The emitter resistors we used worked fine. Every time we had to switch devices to another production run we would double check the bias.

Pretty impressive when you realize that the Reference series were designed to operate into 1/2 ohm per channel.Īs far as the bias goes all amplifiers were adjusted in the lab to just above the appearance of crossover distortion not at a predetermined voltage. Usung these devices we built over 120.000 amplifiers in 17 years, and we did not have any failure problems. You could actually get away with less devices for the same power level. Especially if you put a filter in limitimg them to 100 ms, This information was determined by getting a SAO chart from the manufaturers, Motorola and TI, showing operation to 100ms, which increased the sOA to about 1.4x.
The TIP102/TIP107 have a much better SOA rating. But he never looked at the Safe Operating Area.
I'm guessing he switched to them because they were higher current devices. Those were used by the engineer that designed the Rubicon series. MOER, I never designed any amps using the TIP142/TIP147. I also can repair any Soundstream Old Ochool and Rubicon amps. If youi or anyone else has any more questions please feel free to contact me. Give me a better description of what you were asking and i will answer you.

The tarantula was based on Pro amp that was part of Stewart World Series amplifier line. I had a Pro Audio brand named Stewart electronics. I also designed the tarantula and Davinci. I also designed all heat sinks, power and output connectors and rca input jacks. Also is it also true that the only issue with the amps were the ratings only spec'ed power supplies? Are you talking about thgere power ratings? Can anything be done with the factory D series amp to provide more margin in the power supply? Are you asking if you can get more power out of thge amps by modifying the power supplies? I designed the MC series, Reference series, the later CA series, Granite, uSA and SA series. I also added the CA100 an adaptation based on Nelsons original designs.Ĭould you give me a clearer description of exactly waht you mean when you asked.

In the II series I re-laid them out on single PC Boards, then my company began manufacturing them. All I did tto solve this problem was to re-adjust the bias to a lower setting.
A condition where the bias is set to high and over time the amps would overheat and shut down. They were laid out with point to point wiring which meant that they were not cost effective to build. Feel free to email me if you neeed a second or third opinion.be blessed.Click to oystg, The original D60, D100, D200, CA40 and CA50 were designed by Nelson Pass. If you stick with an excellent company (such as Soundstream) it's hard to go wrong. Amps of this type are hard to find.most will be used. I had infinity 6.5" components for the other 4 channels. I had this amp driving 4 Blaupunkt pcwg120 (12" subs which are of medial quality at best compared with todays new stuff) which created a 1 ohm load for this amp. I am running a pair of '06 Type R, Alpine Coaxials up front, and a pair of Kenwood Dual Mag Components in the rear. Weakness: Honestly, this amp seems a touch on the weak side in the front four channels. What does that mean to you? Well, as the impedandance load gets lower the amp produces more power (if it's made to do such). Strength: Ease of installation, extremely high-end build quality, clean, distortion-free, sound. Maybe 50 -75 watts per channel.However, that hungry beast of a sub or 2 or maybe 4 is hangin' out there looking for some juice. Now, I'm no car audio whiz per say but the need for lots of power in the mids and highs is unnecessary. Talk about an awesome amp!! If you want an amp with the flexibility to power your whole system ( 5 channels) with plenty of power and to also handle those low impedance loads.
