Do you have an Arthur Loesch, DIY Loesch, or other Loesch-designed amplifier or preamp that was fabricated by another maker and is 10, 15, or 20 years old? We've made several circuit changes over the years and can bring your vintage gear up to date (or reasonably close). In addition to modifying the circuit, we can also perform the following:
An example of an updated Loesch-designed amplifier is shown above and below.
- Upgrade capacitors and resistors to match or approximate those in our new units
- Test and replace aging tubes
- Upgrade the RCA sockets and binding posts
- Shorten the signal path, wherever possible
- Replace the original signal path wire with Teflon-jacketed pure silver wire
- Replace the fixed power cord with an IEC connector

If you have an original GenRad 1201A, 1201B, or 1201C power supply for your preamp, we can take it apart and replace all of the old caps and resistors with modern, 1% matches. Those PSUs date from the 1950s and their components often deviate from their stated values by up to 20%. We can also rewire it with larger gauge, color-coded, Teflon-insulated leads.
