Vox UL710 (continued)

Some more details on the 710, picking up from the immediately below.


Further anomalies in the schematics

i) In the unnumbered schematic the 100K resistor that appears in all production amps, standing between the input sockets and the grid of the ECC83 that drives the reverb, is absent. It is however registered as R24 in schematic OS/112.

ii) Conversely, OS/112 envisages two cathode capacitors – C9 and C15.  These are not registered in the unnumbered schematic, and do not appear in the amps as built.

Thanks again to Tuomo for the info.


Serial number 1047


A 710 amp (number unknown) put through its paces

The dates and so on mentioned in the preamble need a little revising, but fine playing.
