After many requests to work on these amps I have finally agreed to take them on! We have done many in the last two years, with great reviews from satisfied Webb owners.
I initially got the info from Brad Sarno on the preamp mod he had been doing. I am going a bit further with the EQ board and the Power Amp upgrade as well with my service.
The upgrade replaces all electrolytic caps with new caps. All are equal or better than the original parts. The main filter caps I have seen so far are huge! Modern days capacitors in the same ratings are much smaller in physical size. The old 614E schematics call for 5,500uf to 10,500uf caps at 75VDC. I am using an excellent grade replacement power filter cap. It is be an 8,200 uf rated at 63 volts for the 50 volt rails. As this power amp is almost a mirror of the old Peavey Session 400 that is more than sufficient. The Session 400 used about a 5,000uf cap for DC filtering on the main voltage 50 volts rails.
All audio coupling caps are upgraded to polyester film on the preamp and EQ boards as well as replacing the electrolytic coupling caps on the EQ board.
I also clean all switches and jacks as well.
The cost for the upgrade is is $260.00 and return freight. This upgrade replaces 38 components in the amp.
This does not included other needed repairs.
I am now stocking 250 volt output transistors for these amps, Session 400, Session 500, Vegas 400, Nashville 400 amps as well. Webb used a 250 Volt transistors. Peavey used 140 volt output transistors! This will be an upgrade when doing outputs on a Peavey amp. These run much cooler and sound better as well.
note:
Place a piece of cardboard over the chassis area and tape it in place to protect the electronics.
I do not recommend UPS for a complete amp. I would use FedEx. If just a chassis and it is packed very well UPS could be OK.
Please not use any packing peanuts for shipping!!!!!

Due to a recent home fire we are not doing repairs or amp mods at this time
