Here is a photo of the output transformers that are used with out Mars Kit2 Mk2. At 50 watt output they have a bandwidth from 40Hz to 100kHz. At the rated output of the Mars Kit2 Mk2, they have a bandwidth from under 10Hz to 100kHz. Primary inductance is about 120 Henries. We can also manufacture transformers for your specific needs. Contact us for information.
Here you can see one of our 50watt Output transformers that are designed for wide band width at 50watt. They use large c-cores and stand about 120mm high. These are ideal for Ultra Linear fixed bias amplifiers working with KT88 or similar high power tubes. R6600 a pair. Orders are welcome.
