Laney VC15 - In need of sharper and clearer pdf copy.
Hello everyone, I had check the sticky Laney schemes thread and yes there is a link to a VC15 schemes but it's very fuzzy and hard to read by my old worn eyes.

I would appreciate a clearer copy before I open the one I have sent in.

I'm uncomfortable when probing anything without any documentation but sometimes I do it anyway.haha. Hope to get some feedback here. Thanks in advance.

I had checked the fuzzy VC15 schematic and found that one does not match the VC15 I'm troubleshooting. That one seems to be meant for older VC15 version with spring reverb. This one I'm looking at now has digital reverb board in it. The components numbering do not match. Maybe mine is generation 2 or 3. Hope anyone that have this schematic would share to me.

Thanks in advance people.

Unfortunately, the scheme is as it is.
maybe you can help if you look at the links

Question

Laney series VC .. have spring reverb.
Whether the Digital reverb board on VC15 is original or is subsequently installed.
Set some photos of VC15 and Look "Under the Hood" (photo PCB ...)

Digital reverb Laney incorporates the Cub series amplifiers

The one I'm repairing has never been opened as the glue on the connector and tubes socket are intake until I dismantle. Base on your CUB12R link I may concur that this VC15 uses the FV1 reverb chip board sold by tubeampdoctor.

Had you not point me to the Cub12R scheme I wouldn't dig the net further which I did and found there's 2 version of Laney VC15. Looking at both from the back where the PT and OT are position. Ver 1 must be with spring reverb and later replaced with the digital one.

The amp I'm checking has treble disappearing act but to my ears its fine as it is. All controls are responding well. There's popping sound trailing the outputting when reverb is turn up. Turn off the reverb and its fine. I re soldered all three pcb just in case.

I have to return back this amp today as he needs it back. Maybe in future I'll have a second chance at it. Thank you Vintagekiki for the enlightment. I am very grateful for your shared research.

I had emailed Laney for the schematics and their reply was positive. From the schematic provided I can now confirm that all post 2009 VC15-110 has digital reverb. All VC15 before 2009 uses spring reverb.Thank you.
