Yours has the daughter board. I forgot to include circuit #5 as the other revision that used the daughter board (previous post now corrected).

Okay which one is mine then because I thought the daughter board was the floating tray, because mine is circuit 5, and it def has that "floating tray" on top of the regular board

In circuit revision # 4 and #5, the 'daughter board' replaced the previous discrete FET circuitry on U87Ai circuits.
It can easily be removed, and a few missing passive components and a new 2N3819 FET (properly biased) installed. Once the FET is properly biased, you would be back to the simpler, better-sounding circuitries # 2 and #6.

Okay I see you do not like this circuit board  ;D (Sub board, also called "daughter board, as used in U87Ai with circuit # 04 and #05. K.H.) the mic sounds really full, fuller than I expected on the other hand! Anyway to get rid of that daughterboard and make it as stock as the ones without the daughterboard... ?

Hey Klaus, wondering about buying a 2000's U87. What year were the capsules not sounding right? Thanks.

Your insight is always of assistance. Even or especially if it's something I don't necessarily want to hear. I will attempt to open a discussion with the one gear-er-dashery in my area that carries the manufacturers I'm curious about as well as several on-line establishments I have a relationship with. In the mean time I'll just have to lash myself to the mast and resist the temptation to buy the Distressor I found on Craigslist! Thx,d

First you will come to the Sirens who enchant all who come near them. If any one unwarily draws in too close and hears the singing of the Sirens, his wife and children will never welcome him home again, for they sit in a green field and warble him to death with the sweetness of their song. There is a great heap of dead men's bones lying all around, with the flesh still rotting off them. Therefore pass these Sirens by, and stop your men's ears with wax that none of them may hear; but if you like you can listen yourself, for you may get the men to bind you as you stand upright on a cross-piece half way up the mast, and they must lash the rope's ends to the mast itself, that you may have the pleasure of listening. If you beg and pray the men to unloose you, then they must bind you faster.

O.K. I have replaced every Resistor, I.C. , Transistor. All Electrolytic caps, All tantalum caps andR45 potentiometer on board .372 capstan control. The 8 uf motor cap and the rca411 transistor off board, and had the motor rebuilt.

That only leaves the ceramic caps and the poly/film type caps. and R27 5k ohm pot.

It still does it.

Maybe spamming... maybe not.  I saw the post as it was phrased to be looking for assistance which is why it was not removed [even though this was the first post by the originator of that post - a tell tale sign of spamming]... the other reason it was left up is that this is a frequent question I hear, and perhaps some of the responses will be of assistance to other readers.

Peace
